Hello @shubs 


If you have fixed the issue, Kindly update the Post with the Solution.


The Exception is coming from DFSInputStream with EOFException. Worth checking if the RegionServer having issues has any Zero Length WAL File under the WAL Directory. Or, Enable TRACE Logging on the concerned RegionServer to capture additional details on the concerned Exception. Or, Checking which WAL is being replicated & any FS issues with the blocks associated with the WAL File.
