Connection refused Error

Dear All:
I installed Hadoop-2.6 on Ubuntu 14.10 desktop yesterday and was able to connect to hdfs and run mapreduce job on singlenode yarn setup. Today I am unable to connect with following
anand_vihar@Latitude-E5540:~/hadoop-2.6.0/sbin$ start-yarn.sh
starting yarn daemons
starting resourcemanager, logging to /home/anand_vihar/hadoop-2.6.0/logs/yarn-anand_vihar-resourcemanager-Latitude-E5540.out
localhost: starting nodemanager, logging to /home/anand_vihar/hadoop-2.6.0/logs/yarn-anand_vihar-nodemanager-Latitude-E5540.out
anand_vihar@Latitude-E5540:~/hadoop-2.6.0/sbin$ refresh-namenodes.sh
Refreshing namenode [localhost:9000]
refreshNodes: Call From Latitude-E5540/127.0.1.1 to localhost:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused
Error: refresh of namenodes failed, see error messages above.

I have made no changes to any set up for yesterday. can somebody advise.
Thanks,

Many thanks. I had to re-install hadoop all over and then start the daemons. It works now
