----------------------------------------------

[~angadsingh], Clients can override any configuration by setting <property><name><name/><value><value/></property> in lens-client-site.xml. There should not be any need for taking comma separated key-value pairs for lens.session.params. 

In REST api, all session config can be passed as map of key-value pairs, which open session accepts.

Can you see if you are facing any problem overriding property through lens-client-site.xml?

> We need to set a bunch of hive session params (job conf). It works when sets it via the lens cli through the "set x=y" api, which calls the "/lensapi/session/params" api on the server, which in turn calls HiveSessionService - setSessionParameter method. Only config-driven way to set these for the hive driver is by setting them in hivedriver-site.xml. This seems to be a lens limitation. Only "lens.session.aux.jars" can be set. Similarly we should be able to set "lens.session.params" with a list of comma-seperated key-value pairs as well. Also this, along with lens.session.aux.jars should be settable via a lens-cli config (not just server-side)
