sharkd tu created SPARK-22900: --------------------------------- Summary: remove unnecessary restrict for streaming dynamic allocation Key: SPARK-22900 URL: https://issues.apache.org/jira/browse/SPARK-22900 Project: Spark Issue Type: Improvement Components: DStreams Affects Versions: 2.3.0 Reporter: sharkd tu
When i set the conf `spark.streaming.dynamicAllocation.enabled=true`, the conf `num-executors` can not be set. As a result, it will allocate default 2 executors and all receivers will be run on this 2 executors, there may not be redundant cpu cores for tasks. it will stuck all the time. in my opinion, we should remove unnecessary restrict for streaming dynamic allocation. we can set `num-executors` and `spark.streaming.dynamicAllocation.enabled=true` together. when application starts, each receiver will be run on an executor. -- 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
