[jira] [Commented] (SPARK-7736) Exception not failing Python applications (in yarn cluster mode)

["Esben S. Nielsen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-7736?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14618110#comment-14618110 ] 

Esben S. Nielsen commented on SPARK-7736:
-----------------------------------------

Platform: spark 1.3.0, CDH 5.4.1

To reproduce with pyspark:

---
from pyspark import SparkContext
with SparkContext(appName="raise_uncaught") as sc:
    raise Exception('Fail')
---
$ spark-submit --master yarn-cluster /path/to/my/pythonscript.py

This ends up with the following YARN status:
State:	FINISHED
FinalStatus:	SUCCEEDED
Diagnostics:	Shutdown hook called before final status was reported.

If the exception is thrown before the SparkContext is initialized YARN status displays as expected:
---
from pyspark import SparkContext
raise Exception('Fail')
with SparkContext(appName="raise_caught") as sc:
    pass
---

This ends up with the following YARN status:
State:	FAILED
FinalStatus:	FAILED
Diagnostics: <trace>

It seems (from the Diagnostics message) that  https://github.com/apache/spark/blob/19834fa9184f0365a160bcb54bcd33eaa87c70dc/yarn/src/main/scala/org/apache/spark/deploy/yarn/ApplicationMaster.scala : L118 is hit when exceptions are raised after initializing SparkContext. This also means applications are not retried when failures happen after SparkContext initialization.

> It seems that exceptions thrown in Python spark apps after the SparkContext is instantiated don't cause the application to fail, at least in Yarn: the application is marked as SUCCEEDED.
> Note that any exception right before the SparkContext correctly places the application in FAILED state.
