(Updated April 29, 2013, 8:22 p.m.) Review request for pig. Changes ------- Created PIG-3300 to address the partial filter condition extraction optimization. Addressed the rest of the comments in this patch. Description ------- 1) Fixed cases where partition pushdown was not happening for AND and OR construct 2) Commented out the negative test cases as they were actually not asserting anything. This addresses bug PIG-3173. https://issues.apache.org/jira/browse/PIG-3173 Diffs (updated) ----- http://svn.apache.org/repos/asf/pig/trunk/src/org/apache/pig/newplan/PColFilterExtractor.java 1467858 http://svn.apache.org/repos/asf/pig/trunk/test/org/apache/pig/test/TestPartitionFilterPushDown.java 1467858 Diff: https://reviews.apache.org/r/10035/diff/ Testing ------- Unit tests added and tested few cases manually with hcat.
