Subject [jira] [Updated] (FLINK-12459) YarnConfigOptions#CLASSPATH_INCLUDE_USER_JAR should affect the order of classpath between user jars and flink jars
Date Fri, 10 May 2019 03:32:00 GMT

     [ https://issues.apache.org/jira/browse/FLINK-12459?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Victor Wong updated FLINK-12459:
--------------------------------
    Description: 
When setting YarnConfigOptions#CLASSPATH_INCLUDE_USER_JAR to "LAST", I think the user jars
should come after all flink libs&jars in runtime classpath, including "flink.jar".

But actually it's not:

org.apache.flink.yarn.AbstractYarnClusterDescriptor#startAppMaster !image-2019-05-09-15-04-36-360.png!

I'm not sure if it's an expected behavior, because if a user forgets to mark Flink dependencies
as "provided", it causes conflicts in detached mode.

Can we optimize it like this: [https://github.com/apache/flink/commit/86f264d76b3cfd89346f8c5ab2b8a9e99600aaee]
