Daniel Dai updated PIG-3473: ---------------------------- Fix Version/s: (was: 0.14.0) 0.15.0 > org.apache.pig.Expression should support "is null" and "not" operations > ----------------------------------------------------------------------- > > Key: PIG-3473 > URL: https://issues.apache.org/jira/browse/PIG-3473 > Project: Pig > Issue Type: Improvement > Components: impl > Affects Versions: 0.11.1 > Reporter: Aniket Mokashi > Fix For: 0.15.0 > > > Currently Expression only support BinaryExpressions and Constants. Most of > the other logical expressions (cast, udf) need not be pushed down. But, it > would make sense to be able to pushdown is null and not operations (possibly > negativeexpression). > This change would have impact on LoadFunc's (hcatloader), we need to be > careful and make sure we do this in a backwards compatible way. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
