Subject Re: hbase master not starting
Date Thu, 13 Mar 2008 05:50:48 GMT
hello ,

It might be due to already running Hmaster process , which might have
not stopped when you tried  to stop using stop-dfs.sh . So just grep for
the Hmaster process , kill manually if it's running and then start dfs
again.

Thanks
