       * Currently in tez, the flow of events is thus: "Generate Splits -> Initialize Vertex"

       * phase groups splits using the TezGroupedSplitsInputFormat. However, for bucket map joins
       * the grouping done by this input format results in incorrect results as the grouper has no
       * knowledge of buckets. So, we initially set the input format to be HiveInputFormat
       * (in DagUtils) for the case of bucket map joins so as to obtain un-grouped splits.
       * We then group the splits corresponding to buckets using the tez grouper which returns
       * TezGroupedSplits.
