Esteban Gutierrez resolved HBASE-9925.
--------------------------------------
    Resolution: Later

Resolving for later, we should better fix other replication bottlenecks before we hit some
contention from the NN.

> While doing replication, we open and close the WAL file _every_ time we read entries
to send. We could open/close the reader only when we hit EOF. That would alleviate some NN
load, especially on a write heavy cluster.
> This came while discussing our current open/close heuristic in replication with [~jdcryans].
