------------------------------
> repl load does not lead to excessive memory consumption for multiple
> functions from same binary jar
> ----------------------------------------------------------------------------------------------------
>
> Key: HIVE-16897
> URL: https://issues.apache.org/jira/browse/HIVE-16897
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2
> Affects Versions: 3.0.0
> Reporter: anishek
> Assignee: anishek
> Fix For: 3.0.0
>
>
> as part of function replication we currently keep a separate copy of the
> binary jar associated with the function ( this should be same on the primary
> warehouse also since each hdfs jar location given during creation of function
> will download the resource in a separate resource location thus leading to
> the same jar being included in class path multiple times)
> this will lead to excessive space used to keep all jars in classpath, solve
> this by identifying the common binary jar ( using checksum from primary on
> replica) and not creating multiple copies thus preventing excessive memory
> usage.
