Velmurugan Periasamy, and Qiang Zhang.


Bugs: RANGER-1669
    https://issues.apache.org/jira/browse/RANGER-1669


Repository: ranger


Description
-------

We need to support the original functionality of hive,
1.Scene: the original hive supports sql:show grant user glc;
2.Error?0: jdbc:hive2://10.43.182.241:10000> show grant user glc;
Error: Error while processing statement: FAILED: Execution Error, return code 1 
from org.apache.hadoop.hive.ql.exec.DDLTask. showPrivileges() not implemented 
in Ranger HiveAuthorizer (state=08S01,code=1)
3.Solution?When you integrate the Ranger plug-in into hive, you can't execute 
show grant user glc?
Modify RangerHiveAuthorizerBase.java to achieve the specific implementation of 
showPrivileges,
4.The modified results can continue to support the original functionality of 
the hive.
