Sending this email for getting wider attention. I propose disabling LogicalExpressionSimplifier optimizer rule, because the complexity of that rule and number of bugs that seem to come from there does not justify the expected performance gains - https://issues.apache.org/jira/browse/PIG-2316?focusedCommentId=13124489&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13124489 In general, I think any new code that is significantly complex (ie hard to maintain, and likely source of bugs) should be added to pig only if there are enough gains to justify it. -Thejas
