Hadoop on multiple user mode
Hello I want to configure hadoop so that it is started as user admin and more than one user can launch job. I notice that while i submit job as a guest user, the map process is executed as admin user. I print user home in my main code as well as inside map process. Is there a way span map process a job submitting user?

If you'd like the tasks to use the actual submitting user accounts, you'll need to turn on security, or more specifically use the LinuxTaskController instead of the DefaultTaskController.

Thanks for the response. However I could not find LinuxTaskController in hadoop 2.2.0.

Hi, In MR2 over YARN, you'll need to configure the LinuxContainerExecutor instead. On Tue, Nov 12, 2013 at 2:11 PM, rab ra wrote: > Thanks for the response.
