Examples of org.apache.hadoop.hbase.index.SpatialPartition

org.apache.hadoop.hbase.index.SpatialPartition
Column value is composed of different values. The value to be indexed is in a known offset

    Configuration conf = TEST_UTIL.getConfiguration();
    HTableDescriptor htd = new HTableDescriptor("testIndexPutWithOffsetAndLength");
    HRegionInfo info = new HRegionInfo(htd.getName(), "ABC".getBytes(), "BBB".getBytes(), false);
    HRegion region = HRegion.createHRegion(info, basedir, conf, htd);
    IndexSpecification spec = new IndexSpecification("index");
    spec.addIndexColumn(new HColumnDescriptor("col"), "ql1", new SpatialPartition(20, 2),
      ValueType.String, 18);


    byte[] value1 = "AB---CD---EF---GH---IJ---KL---MN---OP---".getBytes();
    Put p = new Put("row".getBytes());
    p.add("col".getBytes(), "ql1".getBytes(), value1);
