Examples of org.apache.hadoop.hbase.client.HTableInterface.increment()

org.apache.hadoop.hbase.client.HTableInterface.increment()
Increments one or more columns within a single row.
This operation does not appear atomic to readers. Increments are done under a single row lock, so write operations to a row are synchronized, but readers do not take row locks so get and scan operations can see this operation partially completed. @param increment object that specifies the columns and amounts to be usedfor the increment operations @throws IOException e @return values of columns after the increment
