Devaraj Das commented on HBASE-6733:
------------------------------------
The patch should continue to work if at some point of time, log switching
behavior is changed so that the currentPath always points to a valid non-null
path... But for now, yeah, null works as well (and I have checked in the Hadoop
code that the implementation of equals method with a null argument is handled).

> The failure is in TestReplication.queueFailover (fails due to unreplicated
> rows). I have come across two problems:
> 1. The sleepMultiplier is not properly reset when the currentPath is changed
> (in ReplicationSource.java).
> 2. ReplicationExecutor sometime removes files to replicate from the queue too
> early, resulting in corresponding edits missing. Here the problem is due to
> the fact the log-file length that the replication executor finds is not the
> most updated one, and hence it doesn't read anything from there, and
> ultimately, when there is a log roll, the replication-queue gets a new entry,
> and the executor drops the old entry out of the queue.
