Andrew Purtell resolved HBASE-8253.
-----------------------------------
Resolution: Incomplete
Assignee: (was: Jieshan Bean)
Marking as incomplete.
Let me note I've seen this issue in production. The replication queue will
stall until retries are exhausted, but then the corrupt hlog will be dropped
from the queue and queue processing will resume.

> A writting log got corrupted when we forcely power down one node. Only
> partial of last WALEdit was written into that log. And that log was not the
> last one in replication queue.
> ReplicationSource was blocked under this scenario. A lot of logs like below
