Mutiple Zones on ISILON and PHD Versions

Question

Is it possible/supported to run the following ?

We are on OneFS 7.1

1. One ISILON cluster we have two zones.

one zone is used/pointed by UAT Pivotal Hadoop(PHD) cluster

one zone is used/pointed by PRODUCTION Pivotal Hadoop(PHD) cluster

Both PHD clusters are PHD1.1.1 version

Would it be feasible to point two different versions of PHD to the same ISILON cluster (OneFS 7.1)?

one zone is used/pointed by UAT Pivotal Hadoop(PHD) cluster - PHD2.1 (Upgraded from PHD1.1.1 to PHD2.1)

one zone is used/pointed by PRODUCTION Pivotal Hadoop(PHD) cluster - PHD1.1.1

Is the above configuration supported?

Please advice.

Thanks for your help and time.

Abeesam,

It should work with OneFS 7.1.1.x and above, because in 7.1.1.x and above HDFS became access zone aware, so that each access zone has its own HDFS root path. Here is the output from a 7.2 cluster.
