Re: JAVA API for Drill
Thanks Norris
Is there any documentation regarding the usage of these libraries and
functions? As in which function does what.

Have a look at QuerySubmitter
<https://github.com/hnfgns/incubator-drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/client/QuerySubmitter.java>.
It does boilerplate for posting queries on top DrillClient. All remains is
to attach a result listener to perform your custom logic.

Hi Nishith,
As far as I know, I don't think there is any documentation on that. Hopefully the function names are relatively self-explanatory. If not, feel free to ask on this list for clarification.
