Review request for ranger, Don Bosco Durai and Colm O hEigeartaigh.


Bugs: RANGER-1363
    https://issues.apache.org/jira/browse/RANGER-1363


Repository: ranger


Description
-------

It will always print BadCredentialsException in ranger_admin.log when log to 
the system. I checked the codes and found the reason:
First we set the encoder as 'SHA256'.
String encoder="SHA256";
try
{ authentication = getJDBCAuthentication(authentication,encoder); }
catch (Exception e)
{ logger.info("JDBC Authentication failure: ", e); }

Then we set the encoder as 'MD5'.
if (authentication !=null && authentication.isAuthenticated())
{ return authentication; }
if (authentication != null && !authentication.isAuthenticated()) {
encoder="MD5";
......
try
{ authentication = getJDBCAuthentication(authentication,encoder); }
catch (Exception e)
{ logger.info("JDBC Authentication failure: ", e); }

......
}
Since our encoder is 'MD5', we can log to the system successfully but still can 
see the error log for 'SHA256'. I have do some changes for the codes and avoid 
the BadCredentialsException.
