Subject Re: Starting Abnormally After Shutting Down For Some Time

Hi Bing,

Two questions:

- Can you look at the master log and see what's preventing the master
from starting?

- Did you change dfs.data.dir and dfs.name.dir in hdfs-site.xml? By
default it writes to /tmp which can get cleaned up.

J-D
