> When qualifier is not specified, append and incr operation do not work (shell)

> Key: HBASE-20327
> URL: https://issues.apache.org/jira/browse/HBASE-20327
> Project: HBase
> Issue Type: Improvement
> Components: shell
> Affects Versions: 3.0.0, 2.0.0
> Reporter: Nihal Jain
> Assignee: Nihal Jain
> Priority: Minor
> Fix For: 3.0.0, 2.1.0, 2.0.1
>
> Attachments: HBASE-20327.master.001.patch,

> Running the example commands specified in shell docs for "append" and "incr"
> throw following error:
> {code:java}
> ERROR: Failed to provide both column family and column qualifier for
> append{code}
> {code:java}
> ERROR: Failed to provide both column family and column qualifier for
> incr{code}
> While running the same command via java does not require the user to provide
> both column and qualifier and works smoothly.
>
> Steps to reproduce:
> 1) APPEND
> {code:java}
> hbase(main):002:0> create 't1', 'c1', 'c2'
> Created table t1
> Took 0.8151 seconds
>
> hbase(main):003:0> append 't1', 'r1', 'c1', 'value'
> ERROR: Failed to provide both column family and column qualifier for append
> Appends a cell 'value' at specified table/row/column coordinates.
> hbase> append 't1', 'r1', 'c1', 'value', ATTRIBUTES=>{'mykey'=>'myvalue'}
> hbase> append 't1', 'r1', 'c1', 'value', {VISIBILITY=>'PRIVATE|SECRET'}
> The same commands also can be run on a table reference. Suppose you had a
> reference
> t to table 't1', the corresponding command would be:
> hbase> t.append 'r1', 'c1', 'value', ATTRIBUTES=>{'mykey'=>'myvalue'}
> hbase> t.append 'r1', 'c1', 'value', {VISIBILITY=>'PRIVATE|SECRET'}
> Took 0.0326 seconds
> hbase(main):004:0> scan 't1'
> ROW COLUMN+CELL
>
> 0 row(s)
> Took 0.1273 seconds
> {code}
> While the same command would run if we run the following java code:
> {code:java}
> try (Connection connection = ConnectionFactory.createConnection(config);
> Admin admin = connection.getAdmin();) {
> Table table = connection.getTable(TableName.valueOf("t1"));
> Append a = new Append(Bytes.toBytes("r1"));
> a.addColumn(Bytes.toBytes("c1"), null, Bytes.toBytes("value"));
> table.append(a);
> }{code}
> Scan result after executing java code:
> {code:java}
> hbase(main):005:0> scan 't1'
> ROW COLUMN+CELL
>
> r1 column=c1:, timestamp=1522649623090,
> value=value
> 1 row(s)
> Took 0.0188 seconds
> {code}
>
> 2) INCREMENT:
> Similarly in case of increment, we get the following error (shell):
> {code:java}
> hbase(main):006:0> incr 't1', 'r2', 'c1', 111
> ERROR: Failed to provide both column family and column qualifier for incr
> Increments a cell 'value' at specified table/row/column coordinates.
> To increment a cell value in table 'ns1:t1' or 't1' at row 'r1' under column
> 'c1' by 1 (can be omitted) or 10 do:
> hbase> incr 'ns1:t1', 'r1', 'c1'
> hbase> incr 't1', 'r1', 'c1'
> hbase> incr 't1', 'r1', 'c1', 1
> hbase> incr 't1', 'r1', 'c1', 10
> hbase> incr 't1', 'r1', 'c1', 10, {ATTRIBUTES=>{'mykey'=>'myvalue'}}
> hbase> incr 't1', 'r1', 'c1', {ATTRIBUTES=>{'mykey'=>'myvalue'}}
> hbase> incr 't1', 'r1', 'c1', 10, {VISIBILITY=>'PRIVATE|SECRET'}
> The same commands also can be run on a table reference. Suppose you had a
> reference
> t to table 't1', the corresponding command would be:
> hbase> t.incr 'r1', 'c1'
> hbase> t.incr 'r1', 'c1', 1
> hbase> t.incr 'r1', 'c1', 10, {ATTRIBUTES=>{'mykey'=>'myvalue'}}
> hbase> t.incr 'r1', 'c1', 10, {VISIBILITY=>'PRIVATE|SECRET'}
> Took 0.0103 seconds
>
> hbase(main):007:0> scan 't1'
> ROW COLUMN+CELL
>
> r1 column=c1:, timestamp=1522649623090,
> value=value
> 1 row(s)
> Took 0.0062 seconds
> {code}
> While the same command would run, if we run the following java code:
> {code:java}
> try (Connection connection = ConnectionFactory.createConnection(config);
> Admin admin = connection.getAdmin();) {
> Table table = connection.getTable(TableName.valueOf("t1"));
> Increment incr = new Increment(Bytes.toBytes("r2"));
> incr.addColumn(Bytes.toBytes("c1"), null, 111);
> table.increment(incr);
> scan(table);
> }
> {code}
> Scan result after executing java code:
> {code:java}
> hbase(main):008:0> scan 't1'
> ROW COLUMN+CELL
>
> r1 column=c1:, timestamp=1522649623090,
> value=value
> r2 column=c1:, timestamp=1522649933949,
> value=\x00\x00\x00\x00\x00\x00\x00o
> 2 row(s)
> Took 0.0133 seconds
