Hive CLI should issue warning if JARs were changed after starting the CLI.
--------------------------------------------------------------------------
Key: HIVE-2626
URL: https://issues.apache.org/jira/browse/HIVE-2626
Project: Hive
Issue Type: Improvement
Reporter: Jonathan Chang
Assignee: Jonathan Chang
If a user starts a CLI and ADDs a JAR and then the JAR changes, the classes
generated by the query plan may use an older version of the JAR than what gets
shipped to the nodes. A warning should be thrown up if this happens. (Note
this is really bad for some of us who keep really long running Hive CLI
sessions).
