> URL: https://issues.apache.org/jira/browse/FLINK-15598
> Project: Flink
> Issue Type: Bug
> Components: Deployment / YARN
> Reporter: Xintong Song

> Priority: Blocker

>
> 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.
