Hi all , We are trying to work on the Optimizer part of hive . Can anyone point me to a document/link containing how Hive designs it's query plans , what meta data it uses , how it optimizes the plans (pushing down selects etc) ... Iam facing difficulties is reading the source code , so it would be nice if any one point me to the link containing the above data or any document containing the same.
Any help is highly appreciated ! Thanks !
