[jira] [Commented] (PIG-5235) Typecast with as-clause fails for tuple/bag with an empty schema

["Koji Noguchi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-5235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16014449#comment-16014449 ] 

Koji Noguchi commented on PIG-5235:
-----------------------------------

Another display issue I noticed while debugging, 'describe' now shows the types BEFORE the typecast.   For example, {{describe b}} using the script in description would show 

{noformat}b: {mytuple2: (name: bytearray,age: bytearray)}{noformat}

since as part of PIG-2315, I've reset the original user defined schema and let the next typecast foreach take care of this.  Trying to see if I can fix this but may push to another jira.
