I’m trying to get the Kafka ingestion example (http://druid.io/docs/latest/Tutorial:-Loading-Streaming-Data.html) running in a new Docker cluster I’ve been trying to set up and I’m having an issue querying. My docker project can be found here:
Take a look at the read me on how to start it all. Once I have it up and running, I’m just following the example on how to ingest some sample data. I run the sample data in, and I see it announce a new segment. Then I try to query the realtime node and it just hangs and eventually times out. I don’t see many error in the logs when I start up besides one about the overlord not being able to create a table that looks like this:
Caused by: org.apache.derby.client.am.SqlException: Error for batch element #0: Table/View ‘DRUID_CONFIG’ already exists in Schema ‘APP’.
But I’m told that should be ok. The other WARN message I see every so often is:
DEBG ‘druid-coordinator’ stdout output:
WARN [DatabaseSegmentManager-Exec–0] io.druid.metadata.SQLMetadataSegmentManager - No segments found in the database!
If anyone can help me out in figuring out the problem, that would be great!
