Ted Yu commented on HBASE-16672:
--------------------------------

The first copy is part of backup artifacts which should be immutable.
There is no third copy:
{code}
-            finalPath = bulkLoadListener.prepareBulkLoad(familyName, path);
+            finalPath = bulkLoadListener.prepareBulkLoad(familyName, path, 
copyFile);
+            copyFile = false;
{code}
Once hfile is copied to staging dir, there wouldn't be another copy.

> Add option for bulk load to copy hfile(s) instead of renaming

> multiple destinations, this issue adds option which would always copy 
> hfile(s) during bulk load.
