Michael Stack commented on HBASE-23286: --------------------------------------- Ugh. It was my "kill" script. It was doing graceful shutdown so no WALs at time of SCP. Pardon the noise. > Improve MTTR: Split WAL to HFile > -------------------------------- > > Key: HBASE-23286 > URL: https://issues.apache.org/jira/browse/HBASE-23286 > Project: HBase > Issue Type: Improvement > Components: MTTR > Affects Versions: 3.0.0, 2.3.0 > Reporter: Guanghao Zhang > Assignee: Guanghao Zhang > Priority: Major > Fix For: 3.0.0, 2.3.0 > > > After HBASE-20724, the compaction event marker is not used anymore when > failover. So our new proposal is split WAL to HFile to imporve MTTR. It has 3 > steps: > # Read WAL and write HFile to region’s column family’s recovered.hfiles > directory. > # Open region. > # Bulkload the recovered.hfiles for every column family. > The design doc was attathed by a google doc. Any suggestions are welcomed. -- This message was sent by Atlassian Jira (v8.3.4#803005)
