Subject how to adjust locaity calculation in hadoop
Date Mon, 16 Jun 2014 01:13:44 GMT
Dear all,

I want to operate hadoop on the shared filesystem such as NFS, Lustre.

I think locality calulation in this scenario is meaningless 
because local disk is not used.

Is there any configuration parameters not to use locality calculation?
or Id like to know how to adjust locality calculation in hadoop 
which is optimized for the shared filesystem?

Im suspecting localtity wait factor (mapreduce.job.locality.wait.factor) 
is regarding to this, but Im not sure.

Any kind of ideas will be appreciated.
