[jira] Commented: (PIG-824) SQL interface for Pig

Hi, Renato, I think you can check out this http://hadoop.apache.org/pig/docs/r0.7.0/zebra_overview.html Regards, Min On Fri, May 21, 2010 at 9:16 PM, Renato Marroquín Mogrovejo wrote: > Hi out-there!

package org.apache.hadoop.zebra.parse missing
Hi guys, I checked out pig from trunk, and found package org.apache.hadoop.zebra.parse missing. Do you assure this package has been committed? see this link http://svn.apache.org/repos/asf/hadoop/pig/trunk/contrib/zebra/src/java/org/apache/hadoop/zebra/ Min -- My research interests are distributed systems, parallel computing and bytecode based virtual machine.
