getConf

public org.apache.hadoop.conf.Configuration getConf()

Specified by:

getConf in interface org.apache.hadoop.conf.Configurable

setConf

public void setConf(org.apache.hadoop.conf.Configuration conf)

Specified by:

setConf 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 NullableBigDecimalWritables as raw bytes. If neither are null, then BigDecimalWritable.compare() is used. If both are null then the indices are compared. Otherwise the null one is defined to be less.

Specified by:

compare in interface org.apache.hadoop.io.RawComparator

Overrides:

compare

public int compare(Object o1,
                   Object o2)
