John Sichi commented on HIVE-1487:
----------------------------------
Zheng has a private ptest shell script which takes a different approach: it
enumerates all of the .q files, partitions them modulo the degree of
parallelism, and then executes them in separate environments as separate
processes. One advantage is that there's no cross-talk from threading
(although in the long run testing with multithreading for independent tests
would be good for coverage).
I'll send you a pointer.

> HIVE-1464 speeded up serial runs somewhat - but looks like it's still too
> slow. we should use parallel junit or some similar setup to run test queries
> in parallel. this should be really easy as well need to just use a separate
> warehouse/metadb and potentiall mapred system dir location.
