Hello Everyone,
I have noticed Big Data application failed every Sunday around 5 PM, on all 3 Big Data Preprod environment running VM.
What I need to check to verify on the Virtual machines(Those Are Linux boxes-RHEL7.
Can someone help me please.
Errors similar to below appeared on log files on all 3 environments:
2021-06-06 22:04:41,804 WARN org.apache.hadoop.hdfs.server.namenode.ha.EditLogTailer: Exception from remote name node RemoteNameNodeInfo [nnId=namenode37, ipcAddress=vllxb.XYZ.COM
