-----------------------------------------
Added the description, I will resubmit this for HiveQA once that is working.
> support getClientInfo/setClientInfo in JDBC
> -------------------------------------------

> Key: HIVE-18240
> URL: https://issues.apache.org/jira/browse/HIVE-18240
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin

>
> These are JDBC APIs that allow the user of the driver to provide client info
> to the server; the list of the fields supported by the driver is returned as
> a result set by getClientInfoProperties API.
> I've looked at IBM, Oracle, MS etc. docs and it seems like ApplicationName is
> a common one; there's also ClientHostname, etc. that we don't need because
> HS2 derives them already.
> The client will then set these properties via setClientInfo if desired.
> Whether it is desired by any BI tools of significance I've no idea.
> The properties are sent to the server on connect (which is what Microsoft
> seems to do, but in Hive model it's impossible because HiveConnection
> connects in ctor), or on the next query (I don't recall where I've seen
> this), or immediately (which is what I do in this patch).
> The getClientInfo API on the driver side seems completely pointless, so I
> cache clientinfo locally for it.
