Subject [jira] Commented: (PIG-972) Make describe work with nested foreach
Date Tue, 01 Jun 2010 20:58:38 GMT

    [ https://issues.apache.org/jira/browse/PIG-972?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12874235#action_12874235
] 

Daniel Dai commented on PIG-972:
--------------------------------

We should handle describe for a foreach nested alias in two scenarios:
1. Instant feedback: after user issue the foreach statement in Grunt
2. As part of execution: when we run this foreach statement, we will dump the schema for the
nested alias

> Currently Parser can't deal with that. This is because describe is part of Grunt parser
while the rest of nested foreach is handled by the QueryParser
