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.

> Key: SPARK-7736
> URL: https://issues.apache.org/jira/browse/SPARK-7736
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Environment: Spark 1.3.1, Yarn 2.7.0, Ubuntu 14.04
> Reporter: Shay Rojansky
>
> 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.
