Subject Re: how to use hadoop apis with cloudera distribution ?
Date Tue, 08 Mar 2011 17:26:00 GMT
Thanks Marco !
I  was trying to use CDH3 with eclipse and not able to know why eclipse
complains for the import statement for hadoop apis when cloudera already
includes them.

I did not understand how CDH3 works with eclipse, does it download hadoop
apis when we add svn urls ?
