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
