> I understand the need for hive-jdbc jar (and I assumed it was already on
the Tez CP) but do you know what class it needed from the hive-service.jar? We
should definitely document this? Would you mind adding a wiki to the hive docs
( we need to document this feature anyhow)
@nrg4878 If you submit a query which joins two hive-jdbc remote table, a
tez task should be launched. And if hive-service.jar is not in Tez classpath,
Tez task will faill with the following exception:

I'd love to add this note to the hive docs, and i think we maybe document
here?https://cwiki.apache.org/confluence/display/Hive/Data+Connectors+in+Hive
Could you please give me write access on this docs page? My usename is
`zhangbutao`, thanks.
