Hello,   I would like to ask you some questions about the usage of Isilon. First of all, which do you consider that are the best practices of the architecture of a cluster comparing Isilon HDFS with CDH HDFS at the moment? Do you think that Isilon has limitations comparing with CDH HDFS eg security(sentry,kerberos,ldap), performance, etc? Could I combine the two above solutions eg     1. extending an existed CDH HDFS cluster with Isilon     2. using of Isilon as a backup of an existed CDH HDFS cluster or I have to create a new cluster which uses only Isilon?   Finally, as I can see Isilon is not supported from CDH 6.2. Which will be the next version of CDH which will support it?   Thank you very much, Lefteris Souvleros ... View more
