--------------------------------------
Summary: Change ownership of the directory to bulk load
Key: HBASE-8495
URL: https://issues.apache.org/jira/browse/HBASE-8495
Project: HBase
Issue Type: Improvement
Components: mapreduce
Affects Versions: 0.95.0, 0.94.7
Reporter: Matteo Bertozzi
Priority: Trivial
Fix For: 0.95.2
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.
