Thomas Graves created SPARK-3632: ------------------------------------ Summary: ConnectionManager can run out of receive threads with authentication on Key: SPARK-3632 URL: https://issues.apache.org/jira/browse/SPARK-3632 Project: Spark Issue Type: Bug Components: Spark Core Affects Versions: 1.1.0 Reporter: Thomas Graves Assignee: Thomas Graves Priority: Critical
If you turn authentication on and you are using a lot of executors. There is a chance that all the of the threads in the handleMessageExecutor could be waiting to send a message because they are blocked waiting on authentication to happen. This can cause a temporary deadlock until the connection times out. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
