Recently I upgraded my Ambari cluster's server and agent from v22.214.171.124 to v126.96.36.199. I have also performed schema upgrade using ambari-server upgrade
Following this I can see that I get the following alert for the worker nodes in my cluster
hdp-select could not properly read /usr/hdp. Check this directory for unexpected contents. ERROR: Unexpected file/directory found in /usr/hdp: hadoop
I see that yarn.nodemanager.local-dirs and yarn.nodemanager.log-dirs contains path /usr/hdp/hadoop/yarn/local and /usr/hdp/hadoop/log respectively. These alerts have surfaced only after the upgrade was performed.
Any idea what might be the issue? Thanks in advance.
