Till Rohrmann created FLINK-7804: ------------------------------------ Summary: YarnResourceManager does not execute AMRMClientAsync callbacks in main thread Key: FLINK-7804 URL: https://issues.apache.org/jira/browse/FLINK-7804 Project: Flink Issue Type: Bug Components: Distributed Coordination, YARN Affects Versions: 1.4.0 Reporter: Till Rohrmann
The {{YarnResourceManager}} registers callbacks at a {{AMRMClientAsync}} which it uses to react to Yarn container allocations. These callbacks (e.g. {{onContainersAllocated}} modify the internal state of the {{YarnResourceManager}}. This can lead to race conditions with the {{requestYarnContainer}} method. In order to solve this problem we have to execute the state changing operations in the main thread of the {{YarnResourceManager}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
