Review request for hive.


Bugs: HIVE-7167
    https://issues.apache.org/jira/browse/HIVE-7167


Repository: hive-git


Description (updated)
-------

In the case that hiveserver2 uses embedded metastore and hiveserver uses remote 
metastore, this exception comes up when hiveserver2 and hiveserver are started 
simultaneously.

See the bug link:
https://issues.apache.org/jira/browse/HIVE-7167


The idea is to catch any exceptions from concurrent defaultDB and roles 
initializations or privilege insertions, and try createDefaultDB, 
createDefaultRoles and addAdminUsers one more time, if still fails, simply 
return by printing out error msg and stack trace.

Since exceptions are suppressed and consumed, other kind of issues like 
connection failure will not be catchable by HiveMetaStore caller(s), this could 
lead to some problems.
