NO DataNode Daemon on a single node Hadoop 2.2 installation
Hi,
After I run start-dfs.sh, I dont get a datanode daemon. And in the log file
it generates this exception:
"java.io.IOException: Failed on local exception: java.io.EOFException; Host
Details : local host is: "DELL1/127.0.1.1"; destination host is:
"localhost":9000; "
This is my /etc/hosts file:
"127.0.0.1 localhost
127.0.1.1 DELL1"
And I tried putting DELL1 real ip instead of 127.0.1.1, but no use. Please
advise!

Thanks for the feedback. If you need to re-format you should delete both
the NameNode data and the DataNode data dir as the Datanode stores
version information and will not connect to a NameNode with a different
version.

no master file. but slave file has localhost.
I managed to solve it. I had to delete the data dir of the namenode before
I format. And then it worked fine.
