Subject Re: Using NFS mounted volume for Hadoop installation/configuration
Date Mon, 18 Feb 2013 18:14:37 GMT
I'm also maintaining an experimental Hadoop cluster, and I need to modify the Hadoop source
code and test it,  

so just use NFS to deploy the latest version of code, no problem found yet

 I've seen mtab get messed up and refuse to remount if NFS has any hiccups.
