[jira] [Created] (FLINK-3134) Make YarnJobManager's allocate call
asynchronous
Maximilian Michels created FLINK-3134:
-----------------------------------------
Summary: Make YarnJobManager's allocate call asynchronous
Key: FLINK-3134
URL: https://issues.apache.org/jira/browse/FLINK-3134
Project: Flink
Issue Type: Bug
Components: YARN Client
Affects Versions: 0.10.1, 0.10.0, 1.0.0
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: 1.0.0
The {{allocate()}} call is used in the {{YarnJobManager}} to send a heartbeat to the YARN resource manager. This call may block the JobManager actor system for arbitrary time, e.g. if retry handlers are set up within the call to allocate.
I propose to use the {{AMRMClientAsync}}'s callback methods to send heartbeats and update the container information. The API is available for our supported Hadoop versions (2.3.0 and above).
