org.apache.hadoop.hbase.filter.SubstringComparator
public class SubstringComparator
This comparator is for use with ColumnValueFilter, for filtering based on the value of a given column. Use it to test if a given substring appears in a cell value in the column. The comparison is case insensitive.
Only EQUAL or NOT_EQUAL tests are valid with this comparator.
For example:
ColumnValueFilter cvf =
new ColumnValueFilter("col", ColumnValueFilter.CompareOp.EQUAL,
new SubstringComparator("substr"));
