Upgrade ambari 2.1 to 2.4 : failed to restart Atlas & Falcon

dineshc — Wed, 31 May 2017 07:22:04 GMT

I was using Ambari 2.1 to manage HDP 2.3.0 [AWS Community AMI]

I was able to upgrade to Ambari 2.4.0.1 successfully and all agents were also upgraded and started.

When I check the ambari dashboard, Ambari fails to restart Falcon and Atlas.

I tried to restart a couple times but to no avail.

Here are the services I have on my cluster:

HDFS, YARN, MapReduce2, Tez, Hive, Pig, Oozie, Zookeeper, Falcon, Ambari Metrics, Atlas, Slider

Here are the Atlas Metadata Server restart error log:
