------------------------------------

             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.
