--------------------------------
Summary: Make the vcore that Application Master used configurable
for Flink on YARN
Key: FLINK-12152
URL: https://issues.apache.org/jira/browse/FLINK-12152
Project: Flink
Issue Type: Improvement
Components: Deployment / YARN
Reporter: vinoyang
Assignee: vinoyang
Now, for Flink on YARN deployment mode, each am's vcores is specified to 1
(hard code).
In some scene, we found many Akka timeout logs, the Flink web UI cannot be
opened, but it is alive. I think there is no more threads resource to be used
for am. So we suggest that make the vcores num of application master can be
configurable.
