> 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:
> {code}
> hive --hivevar
> INPUT=/user/jenkins/oozie.1371538916178/examples/input-data/table
> --hivevar
> OUTPUT=/user/jenkins/oozie.1371538916178/examples/output-data/hive
> -f script.q
> {code}
> script.q makes use of hive variables:
> {code}
> CREATE EXTERNAL TABLE test (a INT) STORED AS TEXTFILE LOCATION '${INPUT}';
> INSERT OVERWRITE DIRECTORY '${OUTPUT}' SELECT * FROM test;
> {code}
> 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.
