Subject Re: Hadoop 0.23.1 - cluster startup and job test
Date Sun, 13 May 2012 05:04:04 GMT
Hi

start-dfs.sh and start-yarn.sh are now the one you need to use.

Use Localhost:8088 or place ip for web UI , 50070 stuff is same.

Have you checked datanode logs for reason why node not showing.

Have you entered ip details in slaves file and masters file.
