Subject Re: org.apache.hadoop.hbase.regionserver.wal.DamagedWALException: Append sequenceId=8689
Date Thu, 06 Jul 2017 20:55:07 GMT
HBASE-16960 mentioned the following :

Caused by: java.net.SocketTimeoutException: 20000 millis timeout while
waiting for channel to be ready for read

Do you see similar line in region server log ?

Cheers
