I've updated the pull request. > 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: 0.10.0, 1.0.0, 0.10.1 > 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). > https://hadoop.apache.org/docs/stable/api/org/apache/hadoop/yarn/client/api/async/AMRMClientAsync.html -- This message was sent by Atlassian JIRA (v6.3.4#6332)
