> As per my understanding, CombineFileInputFormat is creating splits with
> rackname as split location.
> When I use CombineFileInputFormat as the InputFormat for job, job
> initialization fails with following exception :
> 2009-04-28 14:10:40,162 ERROR mapred.EagerTaskInitializationListener
> (EagerTaskInitializationListener.java:run(83)) - Job initialization failed:
> java.lang.IllegalArgumentException: Network location name contains /:
> /default-rack

> at java.lang.Thread.run(Thread.java:619)
> When I changed CombineFileInputFormat to pass just rackname (without '/'), JT
> wrongly resolves the node as /default-rack/<rack-name>.
> Solution is to pass hostnames holding the block(on the rack), instead of
> rackname.
