Task Tracker not starting (or going down quickly after starting)

I have installed a 3 node MapR 3.02 (M3) cluster on CentoOS 6 (VM). I see that tasktracker is always down, It momentarily comes up after I restart the warden but goes down again pretty quickly. I believe it is something to do with volume 'mapr.cldb.internal' not being mounted. in MCS, volume tab I see that volume mapr.cldb.internal is not mounted while the other volume mapr.cluster.root is mounted.

Here are the volume details:
[root@mapr-node1 mapr]# maprcli volume list -columns volumename,mountdir,mounted

mountdir  mounted  volumename         
          0        mapr.cldb.internal 
/         1        mapr.cluster.root  

Any thoughts on how to resolve this and if they are linked what's the best practice on mounting that volume?
