Subject [jira] Commented: (PIG-154) Move DEFINE and STORE parsing into QueryParser from GruntParser
Date Thu, 20 Mar 2008 23:57:27 GMT

    [ https://issues.apache.org/jira/browse/PIG-154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12580972#action_12580972

Alan Gates commented on PIG-154:
--------------------------------

I'm unsure about this thing of adding LODefine.  I know that the way things are set up now,
it's hard to get around.  In general, in the future the pig parser will need to be able to
handle lines that don't generate a real logical plan (define, register, set, etc.).  For now
this is ok, but we need to remember that this isn't the direction we want to go.

Everything else looks good.

> Currently GruntParser handles the parsing of DEFINE and STORE commands, it would be better
to parse these in the main QueryParser since it has better infrastructure for expressions
etc. which are really crucial for parsing UDFs etc.
