I have a two node cluster with both firewalls turned off. Both nodes are aware of each other and I can ping and ssh between them with no problems.
When trying to run “hadoop distcp hdfs://hadoop1:8020/users/hadoop/dir1/filename.txt hdfs://hadoop2:8020/users/hadoop/dir2″ I get the following error:
ERROR tools.DistCp: Invalid arguments:
java.net.ConnectException: Call From hadoop1.aseg.com/192.168.10.244 to hadoop2:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
this error happens using short name, fqn and or IP address.
Thanks in advance for your time and assistance.
