(3 comments)

Looks good, thanks! Just a few small things. Clearly Alex still needs to review this :)

http://gerrit.cloudera.org:8080/#/c/7829/3/fe/src/main/java/org/apache/impala/rewrite/SimplifyConditionalsRule.java
File fe/src/main/java/org/apache/impala/rewrite/SimplifyConditionalsRule.java:

PS3, Line 319:     boolean ret = (rewritten instanceof BoolLiteral && ((BoolLiteral)
rewritten).getValue());
I assume you meant to delete this line

File fe/src/test/java/org/apache/impala/analysis/ExprRewriteRulesTest.java:

Line 436:     RewritesOk("isnottrue(null)", rule, "TRUE"); RewritesOk("isfalse(true)", rule,
"FALSE");
nit next line


PS3, Line 451: rules
as we discussed, it'd be helpful to rename this
