Sahara run command
sudo su -c "hadoop dfsadmin -report
on master node of Hadoop cluster and didn't get result in 300 seconds. It does not look like a network issue, since Sahara successfully run many other commands on the node before that.
Is the environment deployed on VirtualBox? If yes, my guess is that the reason of failure is slow QEMU virtualization. This can be checked by re-running the tests. They might fail in another place, or even pass.
