My application is unable to send data to a multi-node druid setup. Following error is show in application log:
Failed to send message: %sjava.lang.IllegalStateException: Failed to create merged beam: druid:overlord/pageviews
Upon further investigation i found following contents under zk node : /tranquility/beams/druid:overlord/pageviews/data
No task can be seen running on the coordinator console. However there are no errors for any of the druid processes.
I am running coordinator and overlord on same machine and middle manager and historical on another machine. I have setup Mysql as metadata store and using HDFS as deep store.
The same application is able to send data to a single node druid using quickstart configuration. Any idea what could be the issue with setup or tranquility?
