Maybe this has to do with this error… I can’t do |ls| to my own machine
using the command below. Can this be related to the other problem?
Shouldn't I list the files with this command?
|vagrant@hadoop-coc-1:~$ hdfs dfs -ls hdfs://192.168.56.100/
ls: Call From hadoop-coc-1/192.168.56.100 to hadoop-coc-1:8020 failed on
connection exception: java.net.ConnectException: Connection refused; For more
details see: http://wiki.apache.org/hadoop/ConnectionRefused

Hi,
I am trying to copy data using |distcp| but I get this error. Both
hadoop runtime are working properly. Why is this happening?
