Andrew Kyle Purtell resolved HBASE-10914.
-----------------------------------------
Resolution: Incomplete
> Improve the snapshot directory local copy during ExportSnapshot
> ---------------------------------------------------------------
>
> Key: HBASE-10914
> URL: https://issues.apache.org/jira/browse/HBASE-10914
> Project: HBase
> Issue Type: Bug
> Components: snapshots
> Affects Versions: 0.96.0
> Reporter: Harsh J
> Priority: Minor
>
> For tables with a lot of regions, the ExportSnapshot appears to "hang"
> without progress cause it copies the .snapshot directory (which has tiny,
> reference/reference-like files I assume) and does not report its state. Would
> be good if it dumped its state for like say, every 50 files it copies.
> This operation is also sequential, so takes a lot of time, and can be
> improved to do 5-10 threads at a time in parallel perhaps, since the actual
> writes are tiny (i.e. data transfer is no concern) and its mostly just NN
> interaction that's needed here.
