Hello,

I have setup a 3 node hadoop cluster using Cloudera Express 5.7.0. and
installed Dt RTS community edition datatorrent-rts-3.3.0.bin.
Total memory available is 24 GB.

However when I launch PiDemo, containers are not getting allocated. Just 2
/ 3 containers are being allocated. This is error in Stram logs.
