I ran into this same issue. For me it manifested as weird permission denied in MapR's NFS implementation, running in bash, etc was fine. But running in on Mesos, it didn't work (permission denied)(Also thank you to MapR for helping me troubleshoot). Good news, there is a patch.
https://issues.apache.org/jira/browse/MESOS-719 And it's fixed in Mesos 0.23. I applied the patch and recompiled and it worked great, and when I installed 0.23, it also worked great. Good luck.
