----------------------------
Attachment: (was: PIG-3539-1.patch)
> Pig should be able to submit multiple DAG
> -----------------------------------------
>
> Key: PIG-3539
> URL: https://issues.apache.org/jira/browse/PIG-3539
> Project: Pig
> Issue Type: Sub-task
> Components: tez
> Reporter: Daniel Dai
> Assignee: Daniel Dai
> Fix For: tez-branch
>
>
> There could be several scenario Pig want to submit multiple DAG:
> 1. a blocking operator in grunt
> 2. a blocking operator in script (exec, fs)
> 3. break a DAG into two for possible inner DAG optimization
> Pig should use TezSession so that we can reuse AM. TezSession should be a
> thread local variable. For those who use Pig Java API, they will use the same
> AM within a thread, but different AM in another thread.
