Hi

Did you try supplying the script name in hdfs-site.xml as the value for the parameter topology.script.file.name<http://topology.script.file.name>?

Thanks

Hi All,

We setup a cluster with out rackawareness, now that we got right rackawreness script, we wanted
to
Make sure data is rack aware.
How we make sure existing data is rack aware and NN should move copies if all of them are
in the
Same rack?

Thanks,
Sam
