Subject Re: Datanodes fail to start
Date Fri, 15 May 2009 06:25:17 GMT
There should be a few more lines at the end.
We only want the part from last the STARTUP_MSG to the end

On one of mine a successfull start looks like this:
STARTUP_MSG: Starting DataNode
STARTUP_MSG:   host = at/192.168.1.119
STARTUP_MSG:   args = []
STARTUP_MSG:   version = 0.19.1-dev
STARTUP_MSG:   build =  -r ; compiled by 'jason' on Tue Mar 17 04:03:57 PDT
