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

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
