Subject Namenode reboot - namespace
Date Thu, 14 Oct 2010 19:58:49 GMT

I have a small doubt regarding Hadoop. For a cluster without secondary
namenode, a namenode reboots itself after failure.

For a scenario,when a namenode reboots itself, and looses all the namespace
Does the namenode starts a fresh and gather all the namespace information
again from the datanodes?

I want to know if at all it looses the info written on the disk, is it able
to obtain the same from the datanodes in the cluster.
