-------------------------------------
Summary: YARN ApplicationMaster sometimes fails to allocate the
specified number of workers
Key: FLINK-1288
URL: https://issues.apache.org/jira/browse/FLINK-1288
Project: Flink
Issue Type: Bug
Components: YARN Client
Reporter: Robert Metzger
Assignee: Robert Metzger
There seems to be a bug somewhere that Flink fails to allocate a full YARN
cluster.
For example, my cluster has 42 nodes with 46.09 GB each (according to the
NodeManager)
If my Flink client is requesting 41 + 1 (workers + master) containers (with
46GB each), I'm only getting 41 containers (instead of 42).
I've contacted the yarn-dev list already for help and I'm trying to figure out
the cause of the issue.
As a simple workaround, users can just request one more container than they
actually need.
