Subject [jira] [Created] (HIVE-14678) Hive-on-MR deprecation warning is not diplayed when engine is set to capital letter 'MR'
Date Wed, 31 Aug 2016 14:48:21 GMT
Raja Mannem created HIVE-14678:
----------------------------------

             Summary: Hive-on-MR deprecation warning  is not diplayed when engine is set to
capital letter 'MR'
                 Key: HIVE-14678
                 URL: https://issues.apache.org/jira/browse/HIVE-14678
             Project: Hive
          Issue Type: Bug
          Components: Beeline, CLI, Configuration, Hive
    Affects Versions: 2.1.0, 2.2.0
            Reporter: Raja Mannem
            Priority: Trivial


hive> SET hive.execution.engine=mr;
Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider
using a different execution engine (i.e. tez, spark) or using Hive 1.X releases.
hive> 

hive> SET hive.execution.engine=MR;
hive>

This warning seems to be generated only with small letter 'mr' wand not with capital letter
"MR".

generateMrDeprecationWarning() seem to be displaying this warning and is being called in different
classes. 

Ex: https://github.com/apache/hive/blob/master/cli/src/java/org/apache/hadoop/hive/cli/CliDriver.java#L754

https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/Driver.java#L1900
