• Type: Sub-task
• Status: Closed
• Priority: Blocker
• Resolution: Fixed
• Fix Version/s: 1.2.0, 1.3.0, 1.0.3, 1.1.3, 0.98.16, 2.0.0
• Component/s: Coprocessors, security
• Hadoop Flags: Reviewed

Release Note

When split is requested by non-super user, split related notifications for Coprocessor are executed using the login of the request user.
Previously the notifications were carried out as super user.

Description

During recent testing in secure cluster (with HBASE-14475), we found the following when user X (non-super user) split a table with region replica:

The cause was that SecureBulkLoadEndpoint#start tried to create staging dir in hdfs as user X but didn't pass authentication.
