------------------------------------
Summary: Memory accuracy loss in YarnClusterDescriptor may lead to
deployment failure.
Key: FLINK-15598
URL: https://issues.apache.org/jira/browse/FLINK-15598
Project: Flink
Issue Type: Bug
Components: Deployment / YARN
Reporter: Xintong Song
Fix For: 1.10.0
Currently, YarnClusterDescriptor parses/derives TM process memory size from
configuration, store it in ClusterSpecification and validate
ClusterSpecification, then overwrite the memory size back to configuration.
This logic is unnecessary. The memory validation is already covered by creating
TaskExecutorResourceSpec from configuration in TaskExecutorResourceUtils.
Moreover, the memory size is stored in MB in ClusterSpecification. The accuracy
loss may lead to memory validation failure, which prevent the cluster from
being deployed.
