Dear All:

Has anyone encountered this error and if so ho= w 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 t= o the problem rather it seems to be a Ubuntu network problem. I have many ti= mes killed nanenode/datanode/secondary data note, shutdown and restarted, bu= t this error still appears. The only way seems to be re-installing hadoop. P= lease advise or refer.

Many thanks,
