ASF subversion and git services commented on KUDU-2612:
-------------------------------------------------------

Commit 4e724988fb9dc6eeb8cd4b91f46760a03cfa5fde in kudu's branch refs/heads/master from Alexey Serbin
[ https://gitbox.apache.org/repos/asf?p=kudu.git;h=4e72498 ]

KUDU-2612 allow system user to read list of table replicas

It turned out that txn system client wasn't able to send BEGIN_COMMIT to
participating tablets if fine-grained authz is enabled.  Its request to
get the list of tablets for a table was rejected: the system user isn't
granted the METADATA privilege on any of user tables, of course.

This patch addresses that deficiency, bypassing the fine-grained authz
for the MasterService::GetTabletLocations() RPC if the caller is a
service- or super-user.  In addition, tests are added to make sure the
multi-row transaction API works as expected even in the presence of
fine-grained authorization.
