Subject hadoop installation error: localhost: ssh: connect to host localhost port 22: connection refused
Date Thu, 28 Aug 2014 14:25:26 GMT
Can anyone please help me with this installation error?

After I type "start-yarn.sh" :

starting yarn daemons
starting resourcemanager, logging to /usr/local/hadoop/logs/yarn-xxxxxx.out
localhost: ssh: connect to host localhost port 22: connection refused


when I ran jps to check, only Jps and ResourceManager were shown -
NodeManager, NameNode and DataNode were not shown.
