Review request for hive and Sahil Takiar.


Bugs: HIVE-16935
    https://issues.apache.org/jira/browse/HIVE-16935


Repository: hive-git


Description (updated)
-------

We strip sql comments from a command string. The stripped command is use to 
determine which
CommandProcessor will execute the command. If the CommandProcessorFactory does 
not select a special
CommandProcessor then we execute the original unstripped command so that the 
sql parser can remove comments.
Move BeeLine's comment stripping code to HiveStringUtils and change BeeLine to 
call it from there
Add a better test with separate tokens for "set role" in 
TestCommandProcessorFactory.
Add a test case for comment removal in set_processor_namespaces.q  using an 
indented comment as
unindented comments are removed by the test driver.
