Himanwan:
Jps fails on my laptop although JDK1.7.0 is installed. There is no etc/hosts
and the slaves file has one entry called localhost

Hi
But the Hadoop wiki say this is a network issue especially with Ubuntu. Please
look at my paste and follow thru link.
As regards my temporary solution. I have to remove all Hadoop files and re
extract it and start over and then it works for a couple of runs before it
starts all over again.

SecondaryNameNodehadoop@node-17:~$ from that output I could make sure that my
namenode is running well, how bout your namenode, are you sure it's running
well or not?

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
