Swapping join inputs in ASTConverter

    • Fix Version/s: 2.0.0
    • Component/s: CBO
    • Labels:
      None

      Description

      We want that multijoin optimization in SemanticAnalyzer always kicks in when CBO is enabled (if possible). For that, we may need to swap the join inputs when we return from CBO through the Hive AST.
