Hi, There :
  With apache hadoop, I am using linux HA from http://www.linux-ha.org/ and DRBD to provide namenode backup. With mapr distribution M3, I wonder if that trick still works. Does anybody have any experience with that ? I understand that if we use M5, we have no need for this. But right now I want to stick with M3 but provide some redundancy for the single instance of CLDB and NFS. Just want to check if anybody has done that or has experience with it.

  Another question I want to ask is that if I can mix M5 and M3 together. For example, I would like to keep the CLDB and NFS nodes to use M5 license, but for datanodes , I just keep M3. Can that work ?
