Re: [Hadoop-studio-users] local debugging?

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

Loris,

The quick answer to your question about debugging is, you can't debug in
that manner, submitting a job to a hadoop cluster, whether local or remote,
is not the same as running a Java program in Eclipse.  The debugging you
can do is you can visually see if your mappers, reducers and such are
working as you expected immediately in the tabs on the workflow.  Also if
there is an exception somewhere in the process of the job running you will
be able to see the exception in the tabs on the workflow and in the log
windows.

Thank you for trying Karmasphere products.

Ted.
