ZEPPELIN-901

How should this be tested?

• Download and install locally Cassandra 3.5
• Start Cassandra
• Clone this pull request locally with:
  • git fetch origin pull/950/head:CassandraInterpreterV3
  • git checkout CassandraInterpreterV3
• Build this version of Zeppelin with mvn clean package -DskipTests
• Start Zeppelin and update the property cassandra.hosts of the Cassandra interpreter (set it to localhost or 127.0.0.1 depending on your configuration)
• To test the ALTER statement, create a new paragraph with the following content:

%cassandra

CREATE KEYSPACE IF NOT EXISTS cassandra_v3 WITH REPLICATION = {'class': 'SimpleStrategy', 'replication_factor': 1};
CREATE TABLE IF NOT EXISTS cassandra_v3.simple(key int PRIMARY KEY);
ALTER TABLE cassandra_v3.simple ADD value text;
DESCRIBE TABLE cassandra_v3.simple;

The result of this paragraph should be:

• To test the support for Zeppelin dynamic form syntax, create a paragraph with the following content:

%cassandra

INSERT INTO cassandra_v3.simple(key,value) VALUES(1, 'first'); 
INSERT INTO cassandra_v3.simple(key,value) VALUES(2, 'second');
INSERT INTO cassandra_v3.simple(key,value) VALUES(3, 'third');

SELECT * FROM cassandra_v3.simple WHERE key=${key=1};

The result of this paragraph should be:

• To test the legacy syntax for dynamic form, create a new paragraph with the following content:

%cassandra

INSERT INTO cassandra_v3.simple(key,value) VALUES(1, 'first'); 
INSERT INTO cassandra_v3.simple(key,value) VALUES(2, 'second');
INSERT INTO cassandra_v3.simple(key,value) VALUES(3, 'third');

SELECT * FROM cassandra_v3.simple WHERE key={{key=1|2|3}};

The result of this paragraph should be:

• To test the override of AngularObject upon dynamic form, create 2 new paragraphs with the following content

First paragraph content:

%angular

<form class="form-inline">
  <div class="form-group">
    <label for="keyId">Key: </label>
    <input type="text" class="form-control" id="keyId" placeholder="key id ..." ng-model="key_id"></input>
  </div>
  <button type="submit" class="btn btn-primary" ng-click="z.angularBind('key_id',key_id,'PUT_HERE_SECOND_PARAGRAPH_ID'); z.runParagraph('PUT_HERE_SECOND_PARAGRAPH_ID')"> Bind</button>
</form>

Second paragraph content:

%cassandra

INSERT INTO cassandra_v3.simple(key,value) VALUES(1, 'first'); 
INSERT INTO cassandra_v3.simple(key,value) VALUES(2, 'second');
INSERT INTO cassandra_v3.simple(key,value) VALUES(3, 'third');

SELECT * FROM cassandra_v3.simple WHERE key={{key_id=1}};

Replace PUT_HERE_SECOND_PARAGRAPH_ID in the angular code of the first paragraph by the real paragraph id of the second paragraph. Execute the first paragraph, put a value into the input text (3) and click on Bind, you should see the following result:

Hi @doanduyhai :)
Could you change this link to http://zeppelin.apache.org/docs/0.6.0-incubating-SNAPSHOT/manual/interpreters.html ?

[AhyoungRyu]

@doanduyhai Great work indeed!
I saw you removed cassandra-InterpreterSelection.png in this PR. But there is still this image link in cassandra.md. Could you check this one ? :)

[doanduyhai]

@AhyoungRyu PR updated with your remarks
