[jira] [Created] (SPARK-4516) Race condition in netty
Hector Yee created SPARK-4516:
---------------------------------
Summary: Race condition in netty
Key: SPARK-4516
URL: https://issues.apache.org/jira/browse/SPARK-4516
Project: Spark
Issue Type: Bug
Components: Shuffle
Affects Versions: 1.1.0
Environment: Linux, Mesos
Reporter: Hector Yee
The netty block transfer manager has a race condition where it closes an active connection resulting in the error below. Switching to nio seems to alleviate the problem.
14/11/20 18:53:43 INFO TransportClientFactory: Found inactive connection to i-974cd879.inst.aws.airbnb.com/10.154.228.43:57773, closing it.
14/11/20 18:53:43 ERROR RetryingBlockFetcher: Exception while beginning fetch of 1 outstanding blocks
