Yes, you're right. SecureBulkLoad seems solve this issue nicely. I'm planning
to do the similar for un-secure case. Basically creating a folder under hbase
staging directory and use doAs to move files from input folder to this staging
directory and then bulk load files from the newly folder under staging
directory.

> To bulk load something you need to change the ownership of the data directory
> to allow the hbase user to read and move the files, also in the split case
> you must use the hbase user to run the LoadIncrementalHFiles tool, since
> internally some directories "_tmp" are created to add the split reference
> files.
> In a secure cluster, the SecureBulkLoadEndPoint will take care of this
> problem by doing a chmod 777 on the directory to bulk load.
> NOTE that a chown is not possible since you must be a super user to change
> the ownership, a change group may be possible but the user must be in the
> hbase group... and anyway it will require a chmod to allow the group to
> perform the move.
