Review request for pig, Daniel Dai, Mark Wagner, and Rohini Palaniswamy.
Bugs: PIG-3541
https://issues.apache.org/jira/browse/PIG-3541
Repository: pig-git
Description
-------
This patch includes the following changes:
* Implement Input/OutputStats for Tez. (This makes DUMP work.) As of now,
counters cannot be retrieved from Tez DAG, so only filenames are reported.
* Add the error message from DAGStatus.getDiagnostic() for failed DAG. As of
now, backend error messages or stack traces cannot be retrieved from Tez DAG,
so only the id of failed vertex is reported.
* Factor out a few methods/fields that can be used by both MR and Tez into
PigStats. Duplicate code between SimplePigStats and TezStats is minimal now.

Testing
-------
* Updated TestTezLauncher by adding asserts for input/output stats.
* Ran ant test-tez.
* Verified reports for succeeded/failed DAGs-
Success!
Input(s): Successfully read records from:
"hdfs://localhost:57063/user/cheolsoop/foo"
Output(s): Successfully stored records in: "/user/cheolsoop/13"
Failed!
ErrorMessage: Vertex failed vertex_1383071498815_0006_1_01
: DAG failed due to vertex failure. failedVertices:1
killedVertices:0
Input(s): Failed to read data from
"hdfs://localhost:57063/user/cheolsoop/foo"
Output(s): Failed to produce result in "/user/cheolsoop/14"
Thanks,
