more eyes look at the code.

> Key: HBASE-8357
> URL: https://issues.apache.org/jira/browse/HBASE-8357
> Project: HBase
> Issue Type: Bug
> Components: Replication
> Affects Versions: 0.94.3
> Reporter: Feng Honghua
>
> consider this scenario: rs A/B/C, A dies, B and C race to lock A to help
> replicate A's left unreplicated hlogs, B wins and successfully creates lock
> under A's znode, but before B copies A's hlog queues to its own znode, B also
> dies, and C successfully creates lock under B's znode and helps replicate B's
> own left hlogs. But A's left hlogs can't be replicated by any other rs since
> B left back a lock under A's znode and B didn't transfer A's hlog queues to
> its own znode before B dies.
