    Default Step can't read fields from previous step

    I have a small problem in kettle. These are the steps I'm using.

    The error is at the second step saying that it's unable to get fields from the previous step because of an error, but the sql in "Table input" step works fine.
    Any ideas?

    right click on the step -> select "Show input fields" and also see if you are using the same fields in the UDJC step..

    It gives me an error, I don't get any input fileds from previous step. When I check "Show output fields" on the previous step I also get an error saying something like this:

    An error occured finding fields
    Method not supported(org.apache.hive.jdbc.HivePreparedStatement.getMetaData)

    Also, If I try to write output fields of "Table input" step to "Text field output" step, it runs fine, BUT again, if I try "Show output/inout fields", I get an error.
