List of addComparisonOp() Examples

Examples of addComparisonOp()

org.apache.hadoop.hive.ql.index.IndexPredicateAnalyzer.addComparisonOp()
Registers a comparison operator as one which can be satisfied by an index search. Unless this is called, analyzePredicate will never find any indexable conditions. @param udfName name of comparison operator as returnedby either {@link GenericUDFBridge#getUdfName} (for simple UDF's)or udf.getClass().getName() (for generic UDF's).

    IndexPredicateAnalyzer analyzer = new IndexPredicateAnalyzer();


    // We can always do equality predicate. Just need to make sure we get appropriate
    // BA representation of constant of filter condition.
    analyzer.addComparisonOp("org.apache.hadoop.hive.ql.udf.generic.GenericUDFOPEqual");
    // We can do other comparisons only if storage format in hbase is either binary
    // or we are dealing with string types since there lexographic ordering will suffice.

      analyzer.addComparisonOp("org.apache.hadoop.hive.ql.udf.generic." +
