Hive CLI Omnibus Improvement ticket
-----------------------------------

                 Key: HIVE-987
                 URL: https://issues.apache.org/jira/browse/HIVE-987
             Project: Hadoop Hive
          Issue Type: Improvement
            Reporter: Carl Steinbach


Add the following features to the Hive CLI:

* Command History
* ReadLine support
** HIVE-120: Add readline support/support for alt-based commands in the CLI
** Java-ReadLine is LGPL, but it depends on GPL readline library. We probably need to use JLine instead.
* Tab completion
** HIVE-97: tab completion for hive cli
* Embedded/Standalone CLI modes, and ability to connect to different Hive Server instances.
** HIVE-818: Create a Hive CLI that connects to hive ThriftServer
* .hiverc configuration file
** HIVE-920: .hiverc doesnt work
* Improved support for comments.
** HIVE-430: Ability to comment desired for hive query files
* Different output formats
** HIVE-49: display column header on CLI
** XML output format

For additional inspiration we may want to look at the Postgres psql shell: http://www.postgresql.org/docs/8.1/static/app-psql.html

Finally, it would be really cool if we implemented this in a generic fashion and spun it off as an apache-commons
shell framework. It seems like most of the Apache Hadoop projects have their own shells, and I'm sure the same is true
for non-Hadoop Apache projects as well.
