> Allow user's full principal name as owner of MapReduce staging directory in
> JobSubmissionFiles#JobStagingDir()
> --------------------------------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-6792
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6792
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: client
> Reporter: Santhosh G Nayak
> Assignee: Santhosh G Nayak
> Attachments: MAPREDUCE-6792.1.patch, MAPREDUCE-6792.2.patch,
> MAPREDUCE-6792.3.patch
>
>
> Background -
> Currently, {{JobSubmissionFiles#JobStagingDir()}} assumes that file owner
> returned as part of {{FileSystem#getFileStatus()}} is always user's short
> principal name, which is true for HDFS. But, some file systems which are HDFS
> compatible like [Azure Data Lake Store (ADLS)
> |https://azure.microsoft.com/en-in/services/data-lake-store/] and work in
> multi tenant environment can have users with same names belonging to
> different domains. For example, {{[email protected]}} and
> {{[email protected]}}. It will be ambiguous, if
> {{FileSystem#getFileStatus()}} returns only the user's short principal name
> (without domain name) as the owner of the file/directory.
> The following code block allows only short user principal name as owner. It
> simply fails saying that ownership on the staging directory is not as
> expected, if owner returned by the {{FileStatus#getOwner()}} is not equal to
> short principal name of the current user.
> {code}
> String realUser;
> String currentUser;
> UserGroupInformation ugi = UserGroupInformation.getLoginUser();
> realUser = ugi.getShortUserName();
> currentUser = UserGroupInformation.getCurrentUser().getShortUserName();
> if (fs.exists(stagingArea)) {
> FileStatus fsStatus = fs.getFileStatus(stagingArea);
> String owner = fsStatus.getOwner();
> if (!(owner.equals(currentUser) || owner.equals(realUser))) {
> throw new IOException("The ownership on the staging directory " +
> stagingArea + " is not as expected. " +
> "It is owned by " + owner + ". The directory must " +
> "be owned by the submitter " + currentUser + " or " +
> "by " + realUser);
> }
> {code}
> The proposal is to remove the strict restriction on short principal name by
> allowing the user's full principal name as owner of staging area directory in
> {{JobSubmissionFiles#JobStagingDir()}}.
