-----------------------------------------
Summary: ResourceManager fails when num task slots > Yarn vcores
Key: FLINK-4998
URL: https://issues.apache.org/jira/browse/FLINK-4998
Project: Flink
Issue Type: Bug
Components: ResourceManager, YARN Client
Affects Versions: 1.1.3, 1.2.0
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: 1.2.0
The ResourceManager fails to acquire containers when the users configures the
number of task slots to be greater than the maximum number of virtual cores of
the Yarn cluster.
We should check during deployment that the task slots are not configured to be
larger than the virtual cores.
