Examples of org.apache.hadoop.hbase.client.Increment.addColumn()

org.apache.hadoop.hbase.client.Increment.addColumn()
Increment the column from the specific family with the specified qualifier by the specified amount.
Overrides previous calls to addColumn for this family and qualifier. @param family family name @param qualifier column qualifier @param amount amount to increment by @return the Increment object

      Increment even = new Increment(rows[0]);

      for (int i=0;i<numQualifiers;i++) {
        if (i % 2 == 0) even.addColumn(families[0], qualifiers[i], 1);
        else odd.addColumn(families[0], qualifiers[i], 1);
        all.addColumn(families[0], qualifiers[i], 1);
      }


      // increment odd qualifiers 5 times and flush
      for (int i=0;i<5;i++) region.increment(odd, null, false);
      region.flushcache();
