Qian Zhang commented on MESOS-8754:
-----------------------------------
The root cause of this issue is, agent failed to change owner of the executor's
sandbox directory to an inexistent user in {{createSandboxDirectory()}} which
caused [this
CHECK|https://github.com/apache/mesos/blob/1.5.0/src/slave/paths.cpp#L728:L729]
failed.
