Yes. All Hadoop commands. The error message is linked to IP address,a dn I
checked Hadoop wiki, this is a network issue on Ubuntu. Unfortunately, I dont
know much about networks.

Hi All:
I am using Ubuntu 14.10 desktop and Hadoop-2.6 pseudo mode. Start-dfs/Stop-dfs
is normal. However, after a couple of times of usage, when I try to connect to
HDFS,, I am refused connection. Find below
anand_vihar@Latitude-E5540:~$ ssh localhost

If I completely delete Hadoop and re-install, it starts working. Can somebody
advise on this issue.
Many thanks
