Hello @paresh    Thanks for using Cloudera Community. Based on the Post, HBase Service is being impacted owing to the Trace shared by you in the Post with the Solutions attempted. While Complete Logs helps, It appears the Region "1595e783b53d99cd5eef43b6debb2682" Replay via "recovered.wals" is being interrupted owing to EOFException.   When a Region is being Opened, any Contents in the "recovered.wals" are Replayed by reading them & pushing to MemStore. Once the Edits are persisted from MemStore to an Hfile, the "recovered.wals" are Removed.    With the Possibility of DataLoss, You may attempt to Stop HBase > Sideline the RecoveredEdits "hdfs://ha-cluster:8020/hbase/MasterData/data/master/store/1595e783b53d99cd5eef43b6debb2682/recovered.wals" & MasterProcWALs (To avoid any Replay of associated PID) > Start HBase > Verify the Status. Note the "DataLoss" is likely from removing the RecoveredEdits File not persisted yet.    Additionally, You may use WALPlayer [1] for replaying the Contents of RecoveredEdits as well.    Regards, Smarak   [1] https://hbase.apache.org/book.html#walplayer   ...
