Amareshwari Sriramadasu commented on LENS-831:
----------------------------------------------
Just noticed that the patch is including hive-metastore jar as well, but
runtime of hive-metastore can be of different version and if compile time jar
is included it might conflict with deployed version. It should be removed from
ship-jars. Created - LENS-881
> Create a single jar for shipping with hive queries

> Currently a number of jars have to be shipped along with each query apart
> from user extension jars for udf, serde etc. This has two side effects:
> 1. Number of ClassLoader on the hive server increases (potentially causing
> PermGen OOM issues)
> 2. Number of jar localization events in the node manager when executing a
> task.
> The proposal is to bundle these and create a single shaded jar and make it
> available in the binary distribution.
