> The ReplicationLogCleaner has a bug that makes it get stuck in an infinite
> loop when a regionserver crashes. This bug was introduced in the fix for
> HBASE-12865; which makes sure that the loadWALsFromQueues method attempts a
> retry whenever the replication node's cversion is changed in the middle of
> loading the replication queue for the regionservers. However, if this
> scenario actually happens (a regionserver crash in the middle of the
> operation), it will get stuck in an infinite loop.
> It has very serious ramifications because the old WALs are not cleaned up
> because of this and in a high load environment, the file count in the oldWALs
> directory soon exceeds the inode limit and the cluster goes down.
