[jira] Commented: (PIG-305) Nested order by queries return only one key instead of all keys

["Alan Gates (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12613653#action_12613653 ] 

Alan Gates commented on PIG-305:
--------------------------------

At least part of the issue is the logical plan in the above query is not correctly connected together.  This looks related to what Tyson reported in PIG-299.  Don't know whether it's a duplicate or if there are additional issues.  Assigning to Santhosh to at least deal with the parser issues.
