Add '-s' option to SET command that forces substitution
-------------------------------------------------------

                 Key: HIVE-1474
                 URL: https://issues.apache.org/jira/browse/HIVE-1474
             Project: Hadoop Hive
          Issue Type: New Feature
          Components: CLI
            Reporter: Carl Steinbach


The 'set' and 'set -v' commands dump unsubstituted property values. I propose adding an additional '-s' switch that forces substitution of the properties.

{code}
hiveCLI> set
...
hadoop.tmp.dir=/tmp/hadoop-${user.name}
mapred.system.dir=${hadoop.tmp.dir}/mapred/system
...
hiveCLI> set -s
...
hadoop.tmp.dir=/tmp/hadoop-carl
mapred.system.dir=/tmp/hadoop-carl/mapred/system
...
hiveCLI>
{code}
