> --------------------------------------------------------------------------------
>
> Key: FLINK-3418
> URL: https://issues.apache.org/jira/browse/FLINK-3418
> Project: Flink
> Issue Type: Bug
> Components: state backends
> Reporter: Robert Metzger
> Priority: Critical
>
> As you can see for example in the {{YARNTaskManagerRunner}}, our TaskManagers are running in a special UserGroupInformation.doAs(); call.
> With that call, we are manually changing the user from the user starting the YARN NodeManager (our containers are part of that process tree) to the user who submitted the job.
> For example on my cluster, the NodeManager runs as "yarn", but "robert" submits the job. For regular file access, "robert" is accessing the files in HDFS, even though "yarn" runs the process.
> The {{HDFSCopyFromLocal}} does not properly initialize these settings, hence "yarn" tries to access the files, leading to the following exception:
> {code}
> Caused by: java.lang.RuntimeException: Error while copying to remote FileSystem: SLF4J: Class path contains multiple SLF4J bindings.
> SLF4J: Found binding in [jar:file:/yarn/nm/usercache/robert/appcache/application_1455632128025_0010/filecache/17/slf4j-log4j12-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
