Cheolsoo Park commented on PIG-3539:
------------------------------------
[~daijy], I see compilation errors (easy to fix) against Tez trunk-
{code}
[javac]
/Users/cheolsoop/workspace/pig/src/org/apache/pig/backend/hadoop/executionengine/tez/TezJob.java:80:
getDAGStatus() in org.apache.tez.dag.api.client.DAGClient cannot be applied to
(<nulltype>)
[javac] dagStatus = dagClient.getDAGStatus(null);
[javac]
[javac]
/Users/cheolsoop/workspace/pig/src/org/apache/pig/backend/hadoop/executionengine/tez/TezSessionManager.java:87:

[javac] symbol : constructor
AMConfiguration(<nulltype>,java.util.Map<java.lang.String,org.apache.hadoop.yarn.api.records.LocalResource>,org.apache.tez.dag.api.TezConfiguration,<nulltype>)
[javac] location: class org.apache.tez.client.AMConfiguration
[javac] AMConfiguration amConfig = new AMConfiguration(null,
resources, tezConf, null);

Do you mind uploading the patch to the RB? Let's get it reviewed/committed.
> 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
>
> Attachments: PIG-3539-1.patch
>
>
> 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.
