Tranquility DruidBeam - NoBrokersAvailableException: No hosts are available

I am trying to use Tranquility to send an event stream to Druid (https://github.com/druid-io/tranquility#storm)

It seems someone else has posted a similar issue, though I cannot resolve my specific situation (How to debug tranquility “NoBrokersAvailableException: No hosts are available for disco!overlord”?)

I am using ZooKeeper 3.4.6, Apache Storm 0.9.4, Tranquility 0.4.2 and Druid 0.7.3, with default configuration for nearly everything on one test node.

Any ideas?

Tranquility Druid Bean Configuration:

return DruidBeams

.builder(

new Timestamper<Map<String, Object>>() {

private static final long serialVersionUID = 1L;

@Override

public DateTime timestamp(Map<String, Object> theMap) {

LOGGER.info( “DruidBean theMap:” + String.valueOf( theMap ) );

LOGGER.info( “DruidBean timestamp:” + theMap.get(“timestamp”) );

// return new DateTime(theMap.get(“timestamp”));

return new DateTime(System.currentTimeMillis());

}

}

)

.curator(curator)

.discoveryPath(discoveryPath)

.location(new DruidLocation(new DruidEnvironment(“overlord”, “druid:firehose:%s”), dataSource))

.rollup(DruidRollup.create(dimensions, aggregators, QueryGranularity.NONE))

.tuning(ClusteredBeamTuning.create(Granularity.HOUR, new Period(“PT0M”), new Period(“PT10M”), 1, 1))

.buildBeam();

This “NoBrokersAvailableException: No hosts are available” issue seems to also be related to this post: Transient errors during creating new tasks

In general these types of errors are due to misconfiguration. Make sure the service name config for your overlord matches the config set in tranquility.

Just to follow up. Despite these exceptions in my logs, my current Storm Topology will now successfully use Tranquility to send events to Druid. I have validated this via the Druid Coordinator Console and with a few specific Druid queries to ensure data is consumed as expected.

Unfortunately for now, I am ignoring this exceptions as noise.

Below is a sample of these type of stack traces.

Hi Mark, I think you may be hitting the same problem described here:
https://groups.google.com/forum/#!searchin/druid-development/NoBrokersAvailableException/druid-development/PU6njY0gE5U/MxwL7xa5Sz0J

Let me know if that helps.

I don’t think this issue is a simple configuration issue, as I have changed as few settings as possible to get this running. I am pretty sure I am using the default “overlord” setting.

To help with debugging this issue, I have published my test Storm Topology and test environment configuration here: https://github.com/mark1900/druid-sandbox/tree/master/kafka-storm-tranquility-druid-topology-test .

Moreover, I have specifically tested this configuration and was able to reproduce this issue. See below. Let me know if you can see any configuration issues.

Hmm, can you describe your ZK setup?

My ZooKeeper configuration is as follows:

wget http://www.us.apache.org/dist/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

tar -xzf zookeeper-3.4.6.tar.gz

cp zookeeper-3.4.6/conf/zoo_sample.cfg zookeeper-3.4.6/conf/zoo.cfg

cat zookeeper-3.4.6/conf/zoo.cfg

The number of milliseconds of each tick

tickTime=2000

The number of ticks that the initial

synchronization phase can take

initLimit=10

The number of ticks that can pass between

sending a request and getting an acknowledgement

syncLimit=5

the directory where the snapshot is stored.

do not use /tmp for storage, /tmp here is just

example sakes.

dataDir=/tmp/zookeeper

the port at which the clients will connect

clientPort=2181

the maximum number of client connections.

increase this if you need to handle more clients

#maxClientCnxns=60

Hi Mark,

The message “No hosts are available for druid:firehose:simple_test_v7-21-0000-0000” means that tranquility can contact your overlord, but can’t contact the specific task hosting simple_test_v7-21-0000-0000. If it looks like some messages are getting through to Druid and being indexed, this might mean that some tasks are working OK and some are not. Tranquility spawns multiple tasks when sending messages to Druid; at least one for each segmentGranularity period.

This could be a capacity issue or an issue with a specific middleManager. Can you check your overlord web console to see if there are pending tasks that haven’t started running yet? That’d indicate a capacity issue. You could fix that by adding more capacity (you can configure more by setting druid.worker.capacity if you have spare resources on the box, or you can add another box if you don’t have spare resources).

If it’s not a capacity issue, then can you check the logs for your running tasks to see if any of them has announced itself as handling “simple_test_v7-21-0000-0000”? There should be a log message about that.

As per your suggestion, I added the following property to druid-0.7.3/config/_common/common.runtime.properties.

druid.worker.capacity=10

``

Which should get picked up by the middle manager:

java -Xms64m -Xmx64m -Duser.timezone=UTC -Dfile.encoding=UTF-8 -classpath config/_common:config/middlemanager:lib/*:${HADOOP_CONFIG_PATH} io.druid.cli.Main server middleManager &

``

I just tested this configuration, so let me if I missed something. Seems I am still seeing this issue.

The Druid Overlord Console (http://<ip_address>:8090/console.html) has one running task and no pending tasks, as expected. Though, when I first started the Storm Trident Topology I noticed 7 of these “Unable to push events to task”/“NoBrokersAvailableException” log entries inside apache-storm-0.9.4/logs/worker-6703.log within the first 5 minutes of operation. About an hour later I received an additional 5 of these “Unable to push events to task”/“NoBrokersAvailableException” log entries.

In previous tests (Given earlier in this thread), I have noticed that these “Unable to push events to task”/“NoBrokersAvailableException” log entries seem to occur hourly. Not sure if this may relate to my Druid segmentGranularity of HOUR ( MyTranquilityBeamFactory.java ).

Within 5 minutes (7 of these events)

Hi Mark,
do you have your chathandler set to announce ? If not try adding this to middlemanager config -

druid.indexer.task.chathandler.type=announce

Hi Mark,

Are these errors transient? Like, do they just happen once or twice and then things go through? Or do you get a failure message that is not labeled as transient?

I’m asking because it looks like they might just be transient. In that case, they’re probably happening because tasks are taking a little bit longer to start up on middleManagers than expected. The most common reason for this is that you are low on capacity, but if you don’t see any pending tasks, then that’s not what’s going on. Correlating logs from tranquility, the overlord, the middleManagers, and the tasks might help figure out why this is taking longer than expected. This might be worth doing if you have the time.

Otherwise, you could work around slow task startup by setting a warmingPeriod, which will spawn tasks “early” so they’ll be ready in time. This won’t help for the first set of tasks but it will help for every subsequent hour. The warmingPeriod is intended as a way of giving the auto-scaler enough time to spin up new middleManagers if needed, but it can also be used to work around any other reason that tasks might be slow to start up.

druid.indexer.task.chathandler.type=announce

``

The errors do seem to be transient.

Following your advice I updated the warming period of my Druid Bean to 10 minutes.

DruidBeams.builder(

.tuning( ClusteredBeamTuning.create( Granularity.HOUR, new Period( “PT10M” ), new Period( “PT10M” ), 1, 1 ) )

``

The default ClusteredBeamTuning values given below for easy reference:

case class ClusteredBeamTuning(

segmentGranularity: Granularity = Granularity.HOUR,

warmingPeriod: Period = new Period(0),

windowPeriod: Period = new Period(“PT10M”),

partitions: Int = 1,

replicants: Int = 1,

minSegmentsPerBeam: Int = 1,

maxSegmentsPerBeam: Int = 1

) extends Logging

I created a GitHub Druid Issue: https://github.com/druid-io/druid/issues/1448

Any update on this??
I continue to see this error in my production setup and like Mark i am also using storm to push events to druid via tranquility .

And i am also getting partial data from druid.This is a snippet of code which sends data to druid:

Future numSentFuture = druidService.apply(batchOfEvents);
numSent = Await.result(numSentFuture);
I always verify the value of “numSent” with the size of “batchOfEvents” to make sure that all the messages were successfully indexed and still i see data loss when querying druid.

This is critical for us to fix,any workaround is welcome.

Thanks

Rohit

We were finally able to fix this issue by changing the “selectionStrategey” as was suggested in this thread “https://groups.google.com/d/msgid/druid-user/22c5bc3c-39c4-4e79-81b4-9f32354c1201%40googlegroups.com?utm_medium=email&utm_source=footer

Also the root cause of the data loss was not these transient error,rather we were hitting a issue in tranquility “https://github.com/druid-io/tranquility/issues/53”,

Hi Rohit,

How do you set this parameter when sending events through Tranquility API?

Thanks!

Michael

Michael,
This parameter needs to set in the configuration of the indexing service(overlord).
You can add "selectStrategy=equalDistribution” in the runtime.properties of the overlord.

My bad.
This is a dynamic property of the indexing service hence it has to be set via a POST call to "http://<OVERLORD_IP>:/druid/indexer/v1/worker” as mentioned in the document "http://druid.io/docs/latest/configuration/indexing-service.html”.

I was experimenting with multiple configurations during last few days hence got confused.
