I’m trying out Tranquility for the first time and I’m not having much luck. I have reverted my setup to running everything locally on my machine. I downloaded the 0.7.1.1 binary, untarred it, and started up zk, mysql, overlord, coordinator, historical, and the broker with no changes to the configs.
Now I have a Java client using Tranquility 0.4.2 and have basically copied the first java example in the README of the Tranquility page. I have a class that sets up the druidService and saves that reference for later. Then I continually send an event to druidService.apply() and I’m using the Future to make sure it gets acknowledged. I don’t call close() on the service/curator until I shut down the app. The client code is here if you want to look at it: https://github.com/acesinc/json-data-generator/blob/master/src/main/java/net/acesinc/data/json/generator/log/TranquilityLogger.java
When I start clean (like the database and everything are clean), and I start my app, it will send events to Druid and I see druid start a Task. My app gets acknowledgement of sending events and keeps sending them. The events being sent have a timestamp of “now.” So it seems my events are being sent to druid, but I don’t see the Task doing anything in the Task log. And the datasource never shows up. I’ve put the task log, overlord log, and coordinator log here in this gist: https://gist.github.com/andrewserff/da349ed0abbba4f773eb
I feel like it is just a configuration issue in the Tranquility task builder, but I can’t figure out what is wrong.
Also, if I shutdown all the services and restart everything and try to start sending data again, it won’t work any more. The client sits there for a long time waiting for an ack, and druid never starts a task. However, it eventually does ask the sending of the data which is weird. And it will start letting it send more data, but each time, the ack takes like 2 min. And no task ever gets started. In order to get it to work again, I have to remove all the druid/tranquility entries in zookeeper…
Let me know what to try!
