[jira] [Commented] (PIG-2725) PushUpFilter does not work as expected

["Prashant Kommireddi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-2725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13290609#comment-13290609 ] 

Prashant Kommireddi commented on PIG-2725:
------------------------------------------

Seems like this issue is caused when a relation does not have schema associated. As per my discussion with Daniel, seems like this is an assumption Logical optimizer makes across most optimizations. 
I will be closing this JIRA, although documentation needs to be fixed to reflect the same which can be done on a separate JIRA.
