> Some applications need to be able to perform actions (such as launch MR jobs) from map
or reduce tasks. In earlier unsecure versions of hadoop (20.x), it was possible to do this
by setting user.name in the configuration. But in 20.205 and 1.0, when running in unsecure
mode, this does not work. (In secure mode, you can do this using the kerberos credentials).
