[jira] [Commented] (FLINK-10535) User jar is present in the flink job manager's class path

["Till Rohrmann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-10535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16654890#comment-16654890 ] 

Till Rohrmann commented on FLINK-10535:
---------------------------------------

Hi [~yinhua], this is actually an artifact of how the {{ExecutionEnvironments}} work currently. If you start a per-job mode in attached mode, Flink will actually start a session cluster underneath because it could be that your job consists of multiple parts (e.g. by using eager execution calls like {{collect}} and {{print}} when using {{DataSet}} API). Therefore, we follow the session cluster code path which first starts the cluster and then uploads the user code jars.

In the future this will change once we update how the {{ExecutionEnvironments}} work. Therefore, I will close this issue.

>             Project: Flink
>          Issue Type: Bug
>          Components: YARN
>    Affects Versions: 1.5.0, 1.6.1
>            Reporter: yinhua.dai
>            Priority: Major
>
> Run flink on yarn with attach and per-job mode, i.e. 
> {code:java}
> flink run -m yarn-cluster -yn 1 *** user.jar
> {code}
> The user.jar will not be present in flink job manager's class path, but as we observed that in flink 1.3 it will by default put to the beginning of flink job manager's class path.
