Duo Zhang commented on HBASE-23286:
-----------------------------------
On the pasted snippet, I do not think it relates to the new feature? The SCP
just consider the log splitting directory as empty and delete it, we have not
even reached the 'split to HFile' code...
Mind uploading more logs here? I think [~zghao] has already ported the patch to
our internal branch-2 based branch and tested the feature?
> 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.
