Andrew Or created SPARK-12133: --------------------------------- Summary: Support dynamic allocation in Spark Streaming Key: SPARK-12133 URL: https://issues.apache.org/jira/browse/SPARK-12133 Project: Spark Issue Type: Bug Components: Spark Core, Streaming Reporter: Andrew Or
Dynamic allocation is a feature that allows your cluster resources to scale up and down based on the workload. Currently it doesn't work well with Spark streaming because of several reasons: (1) Your executors may never be idle since they run something every N seconds (2) You should have at least one receiver running always (3) The existing heuristics don't take into account length of batch queue ... The goal of this JIRA is to provide better support for using dynamic allocation in streaming. The PR will revert the changes added in SPARK-10955, which warns against using dynamic allocation with streaming. -- 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
