Apache Spark commented on SPARK-21490: -------------------------------------- User 'vanzin' has created a pull request for this issue: https://github.com/apache/spark/pull/18696 > SparkLauncher may fail to redirect streams > ------------------------------------------ > > Key: SPARK-21490 > URL: https://issues.apache.org/jira/browse/SPARK-21490 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 2.2.0 > Reporter: Marcelo Vanzin > Priority: Minor > > While investigating a different issue, I noticed that the redirection > handling in SparkLauncher is faulty. > In the default case or when users use only log redirection, things should > work fine. > But if users try to redirect just the stdout of a child process without > redirecting stderr, the launcher won't detect that and the child process may > hang because stderr is not being read and its buffer fills up. > The code should detect these cases and redirect any streams that haven't been > explicitly redirected by the user. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
