Hi,
I'm not sure if there is a setting to avoid the Namenode removed after hosting
machine of Namenode restart.I found that after successfully installed single
node pseudo distributed hadoop following from your website, the name node
dir /tmp/hadoop-brendan/dfs/name are removed if machine reboot.
What do I miss?
