Description

public static PrunedPartitionList prune(Table tab, ExprNodeDesc prunerExpr,
      HiveConf conf, String alias, Map<String, PrunedPartitionList> prunedPartitionsMap)
          throws SemanticException {

vs

  public PrunedPartitionList getPrunedPartitions(String alias, TableScanOperator ts)
      throws SemanticException {
    PrunedPartitionList partsList = opToPartList.get(ts);

Only the 2nd one hits the PPR cache.
