Sean Owen updated SPARK-20989: ------------------------------ Priority: Minor (was: Major) I'm not clear that this is intended to work this way, but if it's not, maybe the error could be clearer. > Fail to start multiple workers on one host if external shuffle service is > enabled in standalone mode > ---------------------------------------------------------------------------------------------------- > > Key: SPARK-20989 > URL: https://issues.apache.org/jira/browse/SPARK-20989 > Project: Spark > Issue Type: Bug > Components: Deploy, Spark Core > Affects Versions: 2.1.1 > Reporter: Jiang Xingbo > Priority: Minor > > In standalone mode, if we enable external shuffle service by setting > `spark.shuffle.service.enabled` to true, and then we try to start multiple > workers on one host(by setting `SPARK_WORKER_INSTANCES=3` in spark-env.sh, > and then run `sbin/start-slaves.sh`), we can only launch one worker on each > host successfully and the rest of the workers fail to launch. > The reason is the port of external shuffle service if configed by > `spark.shuffle.service.port`, so currently we could start no more than one > external shuffle service on each host. In our case, each worker tries to > start a external shuffle service, and only one of them successed doing this. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
