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.
