Vinod Kone resolved MESOS-17.

    Resolution: Fixed

This shouldn't be a problem anymore with the latest Hadoop refactor.

When using the LXC isolation module, this can cause the Hadoop executor's memory allocation
to be reduced before the task actually commits. When this happens, the Hadoop executor is
sometimes killed for exceeding its memory allocation, leaving the tasks stalled until the
master detects the lost task tracker by timeout.
