      Description

      Previous Hive CLI allows user to specify hive variables at the command line using option "--hivevar". In user's script, reference to a hive variable will be substituted with the value of the variable. In such way, user can parameterize his/her script and invoke the script with different hive variable values. The following script is one usage:

      hive --hivevar
           INPUT=/user/jenkins/oozie.1371538916178/examples/input-data/table
           --hivevar
           OUTPUT=/user/jenkins/oozie.1371538916178/examples/output-data/hive
           -f script.q
      

      script.q makes use of hive variables:

      CREATE EXTERNAL TABLE test (a INT) STORED AS TEXTFILE LOCATION '${INPUT}';
      INSERT OVERWRITE DIRECTORY '${OUTPUT}' SELECT * FROM test;
      

      However, after upgrade to hiveserver2 and beeline, this functionality is missing. Beeline doesn't take --hivevar option, and any hive variable isn't passed to server so it cannot be used for substitution.

      This JIRA is to address this issue, providing a backward compatible behavior at Beeline.
