Jiang Xingbo created SPARK-20989: ------------------------------------ Summary: 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
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
