Hi everyone,We have experienced a slowdown on writes and we have seen this error in the rest servers log : org.apache.hadoop.hbase.regionserver.wal.DamagedWALException: AppendĀ sequenceId=8689, requesting roll of WAL I have not seen any issues in the region server or master log files. A few minutes later the performace got back to normal. Has anyone experiences such an issue? Thanks
