Dear Sandeep:
many thanks. I did find hosts, but I do not have write priveleges, eventhough I
am administrator. This is strange. Can you please advise.
Thanks

Hi Anand,
You should search /etc directory in root not Hadoop directory.

Dear All:
Has anyone encountered this error and if so how have you fixed it other then
re-installing Hadoop or re-starting start-dfs.sh when you have already started
after boot. Find below

I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no
fix to the problem rather it seems to be a Ubuntu network problem. I have many
times killed nanenode/datanode/secondary data note, shutdown and restarted, but
this error still appears. The only way seems to be re-installing hadoop. Please
advise or refer.
Many thanks,
