Not exactly the same but ... regarding the security side of things, we
have a similar situation where the cluster is shared by different
users.
As our jobs are Java M/R (no streaming) we force the task JVM to run
with the security manager using an admin provided java policy file to
control what resources jobs can access, in the slaves and in the
network.
We're talking about that in the bug HADOOP-3675 [
https://issues.apache.org/jira/browse/HADOOP-3675 ] . Is it possible for
you to publish the security manager you use ?
Your comments are very welcome
Thanks
