Trying to run map reduce using below cmd and it's failing. Any insights about this error?

yarn jar /usr/hdp/current/hadoop-mapreduce-client/hadoop-mapreduce-examples.jar teragen -Dmapreduce.job.queuename=default 100000000 ${P}/test-${i}

It looks like you have issues with your Resource Manager1 and your app is trying to switch over to Rresource Manager2. You can take a look at RM1 logs to see what the error is. It is either down or not responding on 8032 on time.

Thank you Ravi.

HA Zookeeper Connection State: Auto Failover is not enabled, after enabling this it worked.
