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.
