Re: Trying to run TestRCFile.java

Hello Yin,

I tried doing that by downloading and unzipping a fresh tar ball but the
build fails with the following errors:

Any idea what these are? How to resolve them?

I personally do not have a lot of idea on remote debugging Hive. So a step
by step manual if present would be of great help.

Thanks and Regards,
Mainak.

Hi Mainak,

Can you try 'ant test -Dtestcase=TestRCFile'? It should work.

Thanks,

Yin
