IMPALA-9047: Bump CDP_BUILD_NUMBER to 1471450
This patch bumps CDP_BUILD_NUMBER to 1471450. The new GBN upgrades
Ranger from 1.2 to 2.0, which includes the change to the default Ranger
policies described in https://issues.apache.org/jira/browse/RANGER-2536.
Some of the Ranger tests fail, because they assume the older behavior.
To address this issue, this patch temporarily disables those affected
Ranger tests. Specifically, the affected tests in the following test
files are disabled for now.
1. test_authorized_proxy.py
2. test_ranger.py
3. AuthorizationStmtTest.java
4. RangerAuditLogTest.java
IMPALA-8842 part 2: (Hive3) Use 'engine' field in HMS stat API
The new CDP GBN includes the fix for HIVE-22046. HIVE-22046 added
'engine' column to TAB_COL_STATS and PART_COL_STATS HMS tables. The new
column is used to differentiate among column stats computed by
different engines. The related HMS API calls were changed accordingly.
Part of this patch is Step 4 in a series of steps to coordinate the
introduction of HMS API changes to Hive3 and Impala. For more
information see IMPALA-8842 part 1. Step 4 replaces *V2 calls with *.
The *V2 names were introduced temporarily and will be removed from the
HMS API in the near future.
Testing:
This patch passes the affected Ranger tests listed above on a local
machine.
E2E tests were added to make sure that column statistics are
differentiated by engine for partitioned and non-partitioned tables.
The tests are executed for transactional and non-transactional tables.

> With newer Hive versions, Impala and Hive stats are kept separately and won't
