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 Welcome to Ubuntu 14.10 (GNU/Linux 3.16.0-34-generic x86_64)
