[jira] Updated: (PIG-1086) Nested sort by * throw exception

["Richard Ding (JIRA)" <ji...@apache.org>]

Richard Ding updated PIG-1086:
------------------------------

    Attachment: PIG-1086.patch

The cause of this bug is that the schema of the project (*) operator isn't set correctly before applying ProjectStarTranslator and therefore project (*) operator isn't  translated to a list of projection operators. This causes the inconsistency (and the exception). This patch provides a fix.
