> 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.
