PigTupleSortComparator

public PigTupleSortComparator()
Method Detail

setConf

public void setConf(org.apache.hadoop.conf.Configuration conf)
Specified by:
setConf in interface org.apache.hadoop.conf.Configurable

getConf

public org.apache.hadoop.conf.Configuration getConf()
Specified by:
getConf in interface org.apache.hadoop.conf.Configurable

compare

public int compare(byte[] b1,
                   int s1,
                   int l1,
                   byte[] b2,
                   int s2,
                   int l2)
Compare two NullableTuples as raw bytes. Tuples are compared field-wise. If both are null they are defined equal. Otherwise the null one is defined to be less.

Specified by:
compare in interface org.apache.hadoop.io.RawComparator
Overrides:
compare in class org.apache.hadoop.io.WritableComparator

compare

public int compare(Object o1,
                   Object o2)
Specified by:
compare in interface Comparator
Overrides:
compare in class org.apache.hadoop.io.WritableComparator
