Jerry He commented on HBASE-14605:
----------------------------------
This sounds like a regression caused by HBASE-14475?
In HBASE-14475, the entire code block of doing split and compaction is enclosed
in requestUser.doAs(). Remote request user does not carry security credentials
on the server.
I think the fix should probably go back to HBASE-14475 to narrow the doAs scope
there. We only need the access control checking and audit part to be in the
doAS() over there.
We may see other problems (eg. hdfs permissions) because of the change in
HBASE-14475, or it just happen to work over there.
> Split fails due to 'No valid credentials' error when
> SecureBulkLoadEndpoint#start tries to access hdfs
