Examples of org.apache.hadoop.hive.ql.index.IndexSearchCondition

org.apache.hadoop.hive.ql.index.IndexSearchCondition
IndexSearchCondition represents an individual search condition found by {@link IndexPredicateAnalyzer}.

      throw new RuntimeException(
        "Exactly one search condition expected in push down");
    }


    // Convert the search condition into a restriction on the HBase scan
    IndexSearchCondition sc = searchConditions.get(0);
    ExprNodeConstantEvaluator eval =
      new ExprNodeConstantEvaluator(sc.getConstantDesc());
    byte [] startRow;
    try {
      ObjectInspector objInspector = eval.initialize(null);
      Object writable = eval.evaluate(null);
      ByteStream.Output serializeStream = new ByteStream.Output();
