Aljoscha Krettek commented on FLINK-3418:
-----------------------------------------
Where is the logic that does the user change? Could this simply be added to the
copy utilities?
> RocksDB HDFSCopyFromLocal util doesn't respect our Hadoop security

> 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.
