vim created FLINK-12921: --------------------------- Summary: Flink Job Scheduling Key: FLINK-12921 URL: https://issues.apache.org/jira/browse/FLINK-12921 Project: Flink Issue Type: Improvement Components: API / DataSet, API / DataStream Affects Versions: 1.8.0 Environment: flink 1.7.0
jdk8 Reporter: vim This is an example from flink-docs: Consider a program with a data source, a _MapFunction_, and a _ReduceFunction_. The source and MapFunction are executed with a parallelism of 4, while the ReduceFunction is executed with a parallelism of 3. A pipeline consists of the sequence Source - Map - Reduce. On a cluster with 2 TaskManagers with 3 slots each, the program will be executed as described below. !https://ci.apache.org/projects/flink/flink-docs-release-1.8/fig/slots.svg! But after I tried, I found that it was not like this. My result is TaskManager 1 used 3 slot, but TaskManager 2 just used 1 slot. Who else has tested this example? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
