My setup is a 3 node VM cluster as mentioned in Quick Start guide.

When i run Start all services it fails at datanode start with error

@Aman Poonia

Error says:

/home/vagrant/jdk1.8.0_60_x64/bin/java: Permission denied

So can you please check if your Java has 755 (or execute permission) for the user ?

try setting

chmod 755 -R /home/vagrant/jdk1.8.0_60_x64/bin

This didn't work for me so i finally destroyed the setup and recreated a fresh setup. And it worked. Thanks @jk for the pointers.
