Edward Capriolo commented on HIVE-5518:
---------------------------------------
Anecdotally. Anything required as part of an input format needs to be on the
aux_path. They are needed to read the data, where as UDFs need not be on the
aux_path as they are used inside operators. It would be great if we could unify
these concepts without making the classpath needed to launch every job very
large.
> ADD JAR should add entries to local classpath

> Key: HIVE-5518
> URL: https://issues.apache.org/jira/browse/HIVE-5518
> Project: Hive
> Issue Type: Bug
> Components: CLI
> Affects Versions: 0.12.0
> Reporter: Nick Dimiduk
>
> Jars referenced in {{ADD JAR}} statements are not made available on the
> immediate classpath. That means they're useless for scripts which need to
> initialize external output formats for job submission (ie, hbase storage
> handler). Is this expected behavior?
> For example, the table 'pagecounts_hbase' is an hbase table defined using the
> HBaseStorageHandler
