Till Rohrmann created FLINK-21602: ------------------------------------- Summary: Creation of ExecutionGraph happens in main thread Key: FLINK-21602 URL: https://issues.apache.org/jira/browse/FLINK-21602 Project: Flink Issue Type: Sub-task Components: Runtime / Coordination Affects Versions: 1.13.0 Reporter: Till Rohrmann Fix For: 1.13.0
Currently, the {{AdaptiveScheduler}} creates the {{ExecutionGraph}} in the main thread. This also means that we are recovering state in the {{JobMasters's}} main thread. This can lead to instabilities because we are blocking the main thread for too long. I think the creation of the {{ExecutionGraph}} should happen in an {{ioExecutor}}. -- This message was sent by Atlassian Jira (v8.3.4#803005)
