Subject Changing DN hostnames->IPs
Date Thu, 08 May 2008 17:32:18 GMT
Hi,

Will NN get confused if I change the names of slaves from hostnames to IPs?
That is, if I've been running Hadoop for a while, and then decide to shut down all its daemons,
switch to IPs, and start everything back up, will the master/NN still see all the DN slaves
as before and will it know they are the same old set of DN slaves?

Thanks,
Otis
