Following changes are done in BMO memory quota
1) Enabled memory quota per node. The CQD BMO_MEMORY_LIMIT_PER_NODE
(renamed from EXE_MEMORY_LIMIT_PER_CPU) is set to 10240 MB by default.

Old attribute Old value Renamed Attribute New value

2) Changes in EXPLAIN
   Estimated memory per node for all BMOs at ROOT operator
   Estimated memory per instance for every BMO operator
   Memory quota per instance for every BMO operator
3) BMO TDB contains the memory quota per esp instance now.
4) Root TDB now contains the limit per node and estimated memory per node.
   This can be used by WMS to change the memory allocation during
   runtime without compilation. - Not yet implemented.
4) Added a CQD BMO_MEMORY_LIMIT_UPPER_BOUND to gap the memory
   consumed by BMO by the same queries with less number of
5) The unused memory quota is yielded to other fragments in the process
6) Removed the code to limit the ESPs from being assigned to a fragement
   based on the BMO memory quota.
7) Added a new CQD BMO_MEMORY_ESTIMATE_RATIO_CAP to gap the memory
   estimate skew by any one BMO operator to 0.7.
8) To disable the memory quota per node, set BMO_MEMORY_LIMIT_PER_NODE to 0.
9) This memory quota is distributed proportionally based on the estimated memory
   taking into consideration the number of bmo instances per operator and
   the number of nodes available in the cluster to host these instances.
   Hence, this memory quota should be valid in multi-fragments independent of the
   number of fragments in an ESP.
11) Fixed BMO stats WM to be at least the allocated memory.
12) Changed the sort operator to account the bmo memory correctly.

[TRAFODION-2697] Make sure trafodion is member of hbase, hive groups

Few fixes, details listed below.
-- fix an issue where multiple values inserted from a list would return
  error but each value inserted on its own would succeed.
  ex: create table ts (a timestamp);
      insert into ts values ('2017-01-01 10:10:10'), ('2018-01-01 10:10:10');

-- sometimes errors returned from child during hive inserts were not
   being returned. That has been fixed.

-- TRAFODION-2683 extension.
   added a 'p' (prune) option which would cleanse and filter unneeded
   explain output. This helps in reducing output especially
   for larger explains.
>>explain option 'p' select * from dual;

removed obsolete code that used libhdfs to write to hive/text files
Traf had code to write to hive/text files using direct libhdfs
interface from C or through java interface. hive/sequence files
were added later and they are written using java interface.
libhdfs code was made obsolete a while back and is no longer used.
That code has now been removed.
Traf now uses common java interface to write to hive/text and
hive/sequence files.

TRAFODION [2641] User who has MANAGE_STATISTICS privilege can't do update statistics on HIVE tables
TRAFODION [2175] a user should only see specific schemas/tables that he has
   privileges to
Updated the following get commands:
  get schemas (in catalog)
  get tables, indexes (in schema)
  get sequences, views (in schema, in catalog)
  get libraries, procedures, functions, table mapping functions

TRAFODION [1573] Additional GET commands for privileges
  get privileges on table
  get privileges on view
New regression test privs1/TEST125

Fixed bug: user granted MANAGE privilege does not have MANAGE sub-privs
Changed REGISTER_HIVE_OBJECT to be treated as a sub-priv under CREATE
Changed UNREGISTER_HIVE_OBJECT to be treaed as a sub-priv under DROP

PR-1120 [TRAFODION-2584] Add support to register hive schemas in traf MD

ra TRAFODION-2584 Add support to register hive schemas in traf MD
This checkin extends jira TRAFODION-2584 to add support to register
hive schemas(referred to as databases in hive) in trafodion metadata.
Until now, only hive tables and views were registered.
Registering hive schemas would allow certain operations, like
granting/revoking privileges, to be done on a hive schema/database.

Syntax to register/unregister hive schema
  -- register/unregister hive schema hive.sch;

Syntax to show registred hive schemas
  -- get hive registered schemas in catalog trafodion

"showddl schema hive.sch" will now show the ddl for hive database
creation and whether this schema is registered.

showddl and 'get tables in schema' will now return error if that
schema doesn't exist.

regress/hive/TEST007 has been extended with additional tests.

TRAFODION - 2632 Performing update statistics on metadata tables causes issues
Added code to return error and cleanup code a bit:
*** ERROR[9205] UPDATE STATISTICS is not supported for object <metadata table>

Also fixed a problem where privileges on Hive tables that included external
table gave false "no priv" error for the SHOWDDL <hive table> command.
