------------------------------------
Summary: Meta Region First Recovery
Key: HBASE-8631
URL: https://issues.apache.org/jira/browse/HBASE-8631
Project: HBase
Issue Type: Bug
Components: MTTR
Reporter: Jeffrey Zhong
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.
