Subject Connection Refused Error
Date Mon, 20 Apr 2015 10:50:36 GMT
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
