roncenzhao commented on SPARK-22272:
------------------------------------
The jdk bug is not resolved yet.
If spark does not work around it, I think spark should change the default value
of 'spark.file.transferTo' to false in case of this problem.
> killing task may cause the executor progress hang because of the JVM bug

> Key: SPARK-22272
> URL: https://issues.apache.org/jira/browse/SPARK-22272
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.1.1
> Environment: java version "1.7.0_75"
> hadoop version 2.5.0
> Reporter: roncenzhao
> Attachments: 26883.jstack, screenshot-1.png, screenshot-2.png

> JVM bug: http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8132693
> We kill the task using 'Thread.interrupt()' and the ShuffleMapTask use nio to
> merge all partitions files when 'spark.file.transferTo' is true(default), so
> it may cause the jvm bug.
> When the driver send one task to this bad executor, the task will never run
> and as a result the job will hang forever without handling.
