Jeffrey Zhong updated HBASE-8631:
---------------------------------
Attachment: hbase-8631.patch
This patch includes several changes from my integration testing.
1) pick wal firstly inside splitlogworker
2) decrease retries(fast fail) in distributedLogReplay mode so a splitlogworker
won't be blocked(currently server to server retries are set to 100 by default.
It means 50 mins wait)
3) Add support of removing recovering region when a RS has both meta and user
region situation
> Meta Region First Recovery

> We have a separate wal for meta region. While log splitting logic haven't
> taken the advantage of this and splitlogworker still picks a wal file
> randomly. Imaging if we have multiple region servers including meta RS fails
> about the same time while meta wal is recovered last, all failed regions have
> to wait meta recovered and then can be online again.
> The open JIRA is to let splitlogworker to pick a meta wal file firstly and
> then others.
