Till Rohrmann updated FLINK-14582:
----------------------------------
Component/s: Deployment / YARN
> Do not upload {uuid}-taskmanager-conf.yaml for each task manager container
> --------------------------------------------------------------------------
>
> Key: FLINK-14582
> URL: https://issues.apache.org/jira/browse/FLINK-14582
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / YARN
> Reporter: Yang Wang
> Priority: Major
>
> Currently when we {{createTaskExecutorLaunchContext}}, a new task manager
> conf will be created and uploaded to hdfs. The time cost is unnecessary and
> could be reduced by using java options of task manager main class instead.
> By reducing the time of launch container in {{onContainersAllocated}}, we
> could avoid allocating excess containers as much as possible.
