-------------------------------------

             Summary: RocksDB HDFSCopyFromLocal util doesn't respect our Hadoop security configuration
                 Key: FLINK-3418
                 URL: https://issues.apache.org/jira/browse/FLINK-3418
             Project: Flink
          Issue Type: Bug
            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}

I think we need to fix this before the 1.0.0 release.
