Subject [jira] [Updated] (HIVE-5158) allow getting all partitions for table to also use direct SQL path

Phabricator updated HIVE-5158:
------------------------------

    Attachment: HIVE-5158.D12573.1.patch

sershe requested code review of "HIVE-5158 [jira] allow getting all partitions for table to
also use direct SQL path".

Reviewers: JIRA

initial patch. Tests are running.

While testing some queries I noticed that getPartitions can be very slow (which happens e.g.
in non-strict mode with no partition column filter); with a table with many partitions it
can take 10-12s easily. SQL perf path can also be used for this path.
