Jeff Zemerick commented on MAPREDUCE-2449:
------------------------------------------
The call to getAttribute can throw a CoreException if it can't retrieve the
value we're looking for, or if that value is not the type we are expecting (a
String in this case). Typically, the catch block would be used to set some
default value, but I did not do that since the default value in this case is
just an empty string (no parameters). I don't think it's necessary to throw an
RTE. When the run configuration is executed it will overwrite the existing one,
so if the value was invalid for some reason it will be overwritten.
> Allow for command line arguments when performing "Run on Hadoop" action.

> It is currently not possible to specify command line arguments when creating
> a run configuration for "Run on Hadoop." This patch adds a text box to the
> RunOnHadoopWizard dialog for providing command line arguments. The arguments
> are then stored as part of the run configuration. Additionally (as a result),
> this patch prevents the creation of duplicate run configuration creation by
> seeing if the original configuration has been changed first.
