HDP 2.4.2

Ambari 2.2.2

druid-0.9.0

I am following this http://druid.io/docs/latest/tutorials/quickstart.html and running

[root@nss03 druid-0.9.0]# curl -X 'POST' -H 'Content-Type:application/json' -d @Former Member/wikiticker-index.json http://overlordnode:8090/druid/indexer/v1/task

{"task":"index_hadoop_wikiticker_2016-05-24T11:38:51.681Z"}

[root@nss03 druid-0.9.0]#

I can see that job is submitted to the yarn queue. RM UI error details.

@Neeraj Sabharwal possibly a yarn client version difference issue.

I was able to fix the above issue by adding hadoop jars in the class path while starting the components

HDP 2.6 has native support to druid where you don't have to do all this classpath adding.
