[jira] [Created] (SPARK-17300) ClosedChannelException caused by
missing block manager when speculative tasks are killed
Ryan Blue created SPARK-17300:
---------------------------------
Summary: ClosedChannelException caused by missing block manager when speculative tasks are killed
Key: SPARK-17300
URL: https://issues.apache.org/jira/browse/SPARK-17300
Project: Spark
Issue Type: Bug
Reporter: Ryan Blue
We recently backported SPARK-10530 to our Spark build, which kills unnecessary duplicate/speculative tasks when one completes (either a speculative task or the original). In large jobs with 500+ executors, this caused some executors to die and resulted in the same error that was fixed by SPARK-15262: ClosedChannelException when trying to connect to the block manager on affected hosts.
