----------------------------------------------
[~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?
> Add ability to set lens session params via config

> 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)
