[jira] [Created] (FLINK-9410) Replace NMClient with NMClientAsync
in YarnResourceManager
Till Rohrmann created FLINK-9410:
------------------------------------
Summary: Replace NMClient with NMClientAsync in YarnResourceManager
Key: FLINK-9410
URL: https://issues.apache.org/jira/browse/FLINK-9410
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Affects Versions: 1.5.0, 1.6.0
Reporter: Till Rohrmann
Fix For: 1.6.0
Currently, the {{YarnResourceManager}} uses the synchronous {{NMClient}} which is called from within the main thread of the {{ResourceManager}}. Since these operations are blocking, we should replace the client with the {{NMClientAsync}} and make the calls non blocking.
