Subject secondarynamenode
Date Mon, 17 Mar 2008 22:08:11 GMT
Hi,

Anyone have stats for the impact on system resources (disk/memory/cpu) of
running secondarynamenode on a host? Are people running multiple secondary's
for redundancy or just going the route of having the namenode (& secondary)
replicate edits & fsimage to multiple physical disks (and nfs when
possible)?  Basically, I'm trying to determine the possible impact on
performance of running secondarynamenode daemon on several machines, as well
as if there's any potential benefit of running more than 1.

What are other people doing for disaster recovery on namenode?
