Examples of org.apache.hadoop.hbase.client.Put

org.apache.hadoop.hbase.client.Put
Used to perform Put operations for a single row.
To perform a Put, instantiate a Put object with the row to insert to and for each column to be inserted, execute {@link #add(byte[],byte[],byte[]) add} or{@link #add(byte[],byte[],long,byte[]) add} if setting the timestamp.

    // From HBASE-1821
    // Desired action is to combine two SCVF in a FilterList
