Subject Bulk-loading HFiles after table split (on ACL enabled cluster)
Date Tue, 16 Sep 2014 21:26:26 GMT

I can't find mention of this issue on the Jira.  Is it known?  I think that
if a split of the HFiles is required, LoadIncrementalHFiles should create
the new HFiles with the correct permissions to be bulk-loaded. Currently it
just hangs because the permissions are wrong.

Here is how I reproduce my issue:

On a cluster with ACL enabled, I generate HFiles for a bulk-load, then
*force a table split*, and then attempt to bulk-load the HFiles.  The
bulk-load hangs (similar to when the hfiles' directory is not chown'ed

If I chmod -R 777 the directory and try again, the bulk load completes
