TRAFODION-3146 Support ANSI OVERLAY function

OVERLAY modifies a source string by replacing a given

substring of the string, which is specified by a given numeric starting

position and a given numeric length, with a replacement string).

When the length of the substring is zero, nothing is removed

from the source string and the string returned by the function is the

result of inserting the replacement string into the source string at the

starting position.

STUFF is syntactic variation of OVERLAY.

Example:

overlay ('source original string' placing 'modified ' from 8 for 9)

stuff ('source original string', 8, 9, 'modified ')

will return:

'source modified string'

overlay ('source original string' placing 'modified ' from 8 for 0)

will return:

'source modified original string'

TRAFODION-3086 DDL on Hive objs: use database and msck support

-- traf "set schema hive.<sch>" now behaves the same as Hive "use <db>".

1) <sch> is validated to exist at set schema time.

2) <sch> is set in Hive environment for that session. Any unqualified

object reference in ddl uses that default schema (database)

-- added support for msck (meta store check) command.

This command repairs database by refreshing untracked files/partitions

in hive metadata.

TRAFODION-1573: Additional GET commands for privileges TRAFODION-3074: Failed to register/unregister user when security disabled

TRAFODION-1573 changes:

- Added support for the following commands:

get privileges on <object>

<object>: [LIBRARY | PROCEDURE | FUNCTION | TABLE_MAPPING FUNCTION | SEQUENCE]

- Added support for the FOR CLAUSE on all supported objects

Removed the need to specify keyword 'USER" before username. If USER is

included, then it is ignored.

get privileges on <object> FOR [USER] <user or role name>

<objects>: [TABLES, VIEWS, LIBRARIES, PROCEDURES, FUNCTIONS,

TABLE_MAPPING FUNCTIONS, SEQUENCES]

- The following get command can only be run by DB__ROOT or a user that has been

granted the DB__ROOTROLE or DB__HIVEROLE role

get <objects> in schema hive.xx.xx;

<objects>: [TABLES, OBJECTS, VIEWS]

- The following get command can only be run by DB__ROOT or a user that has been

granted the DB__ROOTROLE or DB__HBASEROLE role

get external hbase objects;

- The following get commands retrieve privilege details from Trafodion metadata;

users can only see objects where they have been granted at least one privilege

get hive registered tables in catalog trafodion;

get hbase registered tables in catalog trafodion;

- get privileges commands now return owner's privileges in output

- Cleaned up code in the parser.

TRAFODION-3074 changes

- register user - fixed query to find next available authID

- unregister user - added checks to not read privilege metadata if authorization

is not enabled

traf DTM only supports 'read committed access' for selects

and 'set transaction ' stmts.

With this checkin, only those 2 options will be allowed.

All other access options will return an error.

Read uncommitted access will be treated as read committed.

[TRAFODION-2540] Alter Drop column on table with identity

Bug: Hive inserts with mismatched tgt/src datatypes would sometimes do not

insert or insert incorrect values.

[TRAFODION-2584] Add support to register hive objects in traf metadata

Syntax:

register hive table/view [if not exists] <object-name> [cascade]

unregister hive table/view [if exists] <object-name> [cascade]

cascade option: register/unregister all underlying objects that are

part of the specified view

update statistics, grant/revoke, traf views or external table creation

on hive objects will automatically and internally register those objects

in trafodion metadata.

invoke/showddl will show if this object is registered and whether

that registration was internal or explicit.

Get command extensions:

get hive registered tables/view/objects in catalog trafodion;

get hive external tables in catalog trafodion;

Cleanup command extensions:

cleanup metadata command will clean up inconsistent hive objects

(underlying hive object is missing but object is registered or

an external table exists)

cleanup [hive table | hive view] on <object-name>;

Existing hive objects that had implicit or explicit external tables

created prior to this checkin will have no change in behavior.

ObjectUID of those external tables will continue to be used for

relevant operations.

One can drop those external tables and explicitly register them,

or a subsequent operation(upd stats, grant, etc) that needs objectUID will

automatically register them.

minor changes based on review comments of previous checkin

get all objects command on hive metadata no longer fails.

get views on objects return 3-part name that could be used to

differentiate between a traf and hive view.

regress/hive/TEST007 has been extended.

TBD: Add register/unregister privileges

TRAFODION-2498 Add support to run hive stmts from traf interface

Syntax:

process hive statement '<string>';

<string>: hive statement starting with create/drop/alter/truncate.

These are the only stmts currently supported.

Ex:

>>process hive statement 'create database trafsch';

will create hive database 'trafsch'

>>process hive statement 'create table trafsch.t (a int)';

will create hive table 't' in hive schema 'trafsch'.

'process hive statment ..' could be issued from any traf interface

[TRAFODION-2228]Add AES_ENCRYPT/AES_DECRYPT functions

Add two functions which used to encrypt and decrypt the data using the

official AES (Advanced Encryption Standard) algorithm.

AES_ENCRYPT(str, key_str[, init_vector])

AES_DECRYPT(crypt_str, key_str[, init_vector])

Both these two function have optional init_vector argument which

provides an initalization vector for block encryption modes that

require it. For modes that require the optional init_vector argument, an error

occurs if init_vector is missing. For modes that don't need

init_vector, it will raise a unused argument waring if init_vector is

provided.

The new CQD block_encryption_mode controls the mode for

block-based

encryption algorithm. The default value is 0, which use

aes-128-ecb.

Here is the list for diffferent values for

block_encryption_mode

CQD value algorithm

0 aes-128-ecb

1 aes_192_ecb

2 aes_256_ecb
