> Sometimes, user want to write data and ignore null value to achieve partial
> update. So i suggest adding an options: sink.ignore-null-value.

> {code:java}
> CREATE TABLE hTable (
> rowkey STRING,
> cf1 ROW<q1 STRING, q2 STRING>,
> PRIMARY KEY (rowkey) NOT ENFORCED
> ) WITH (
> 'connector' = 'hbase-2.2',
> 'table-name' = 'default:test',
> 'zookeeper.quorum' = 'localhost:2181',
> 'sink.ignore-null-value' = 'true' -- default is false, true is enabled
> );
> INSERT INTO hTable VALUES('1', ROW('10', 'hello, world'));
> INSERT INTO hTable VALUES('1', ROW('30', CAST(NULL AS STRING))); -- null
> value to cf1.q2
> -- when sink.ignore-null-value is false
> // after first insert
> {rowkey: "1", "cf1": {q1: "10", q2: "hello, world"}}
> // after second insert, cf1.q2 update to null
> {rowkey: "1", "cf1": {q1: "30", q2: "null"}}
> -- when sink.ignore-null-value is true
> // after first insert
> {rowkey: "1", "cf1": {q1: "10", q2: "hello, world"}}
> // after second insert, cf1.q2 is still the old value
> {rowkey: "1", "cf1": {q1: "30", q2: "hello, world"}} {code}
