Re: [Hadoop-studio-users] Workflow GUI Reporter implementation

[Ted R. <tre...@ka...>]

David,

Unfortunately the GUI emulator is not a full-blown Hadoop environment, and
does not have input splits or counters.  The is currently no way to do this
in the emulator.  Your best work around would be to deploy the job to
either the local/embedded Hadoop or to a real Hadoop cluster.
