Junfan Zhang created SPARK-49783:
------------------------------------
Summary: Resource leak of spark yarn allocator
Key: SPARK-49783
URL: https://issues.apache.org/jira/browse/SPARK-49783
Project: Spark
Issue Type: Bug
Components: YARN
Affects Versions: 3.5.0, 4.0.0
Reporter: Junfan Zhang
When the target < running containers number, the assigned containers from the
resource manager will be skipped, but these containers are not released by
invoking the amClient.releaseAssignedContainer , that will make these
containers reserved into the Yarn resourceManager at least 10 minutes. And so,
the cluster resource will be wasted at a high ratio.
Another problem will happen that the vcore * seconds statistics from yarn side
will be greater than the result from the spark event logs.
>From my statistics, the cluster resource waste ratio is ~25% if the spark jobs
>are exclusive in this cluster.
