What is the CLI eq. of "add jar 
I need to pass some custom Java classes that I use as InputFormats and SerDe classes to Hive Queries made from HWI.  I use "add jar <path>" from CLI that works without any issues.  How do I do the same from HWI?

I have set the "hive.aux.jars.path" path where the JAR files are, but that is not passed on to the DataNodes as it's used only for Hive SerDe and not for InputFormat classes that is needed by the MR jobs.

Please advice.

Regards,
Karthik.

Hi Karthik,

Do you have access to the cluster?  The simplest way is to put the jars into
the cluster, $HADOOP_HOME/lib directories on each of the nodes.  This will
require TTs restart though.
