The Rawcomparator and realization of Hadoop-2.4.1 learning

: This class inherits from Writablecomparator and implements the configurable interface. This class provides some of the attributes of Unix/gnu ordering, which are:-N (numeric sort),-R (reverse the comparison), and so on.Next, learn how these two Rawcomparator implementation classes implement byte-based comparisons using the source code of Deserializercomparator and Writablecomparator. The first is the Deserializercomparator class, the implementation code for this class is as follows:@Overridepu

This requires the setOutputProperties () method of the Transformer class. The parameter is a java. util. Properties object. We have compiled a new program that applies the OutputKeys class to control the output attributes of the XSLT engine. The program architecture is roughly the same as that of the previous program (Ad
