Siddharth Seth commented on TEZ-1376:
-------------------------------------

[~airbots] - do the tests currently fail ?
Also, they'll require a longer sleep time to ensure that they're actually 
running concurrently.
Potentially different threads, to ensure that blocking calls in 
TezClient/DAGClient do not end up causing the test to accidentally pass. This 
isn't mandatory though, since these calls return immediately. Is there some way 
we can validate that both dags are running concurrently ?

> Support independent parallel DAGs execution in Local Mode

> Pig on Tez allows user to submit parallel DAGs in a single pig script. Those 
> DAGs could be independent and concurrent. Current LocalMode may encounter 
> some problems when concurrent parallel DAGs are submitted.
