Subject Namenode and metadata backups via NFS
Date Wed, 09 Mar 2011 15:08:12 GMT
Hi there,

We've just set up a Namenode that backups its metadata (as recommended) on an NFS store.
Since this NFS-Mount is not a netapp appliance and can go down anytime,
I just checked what happens if it goes down and found the DFS no longer reacting until it
came back.

Is there some best practice on how to configure NFS-Server or the namenode not to lock / ignore
a mount thats going down?

I'm using CDH beta 2.

Best,

Tobias
