Date Thu, 09 Jun 2016 13:46:22 GMT
Repository: incubator-zeppelin
Updated Branches:
  refs/heads/master 164bcd36a -> 43baa0af4


ZEPPELIN-925 Merge HiveInterpreter into JDBCInterpreter

### What is this PR for?
This removes hive module and adds example setting for using Hive in a JdbcInterpreter by using loading dynamic dependencies. It reduces Zeppelin's binary size.

There's no codes' modification except removing hive directory and remove the module from pom.xml

### What type of PR is it?
[Feature]

### Todos
* [x] - Remove hive module
* [x] - Add an example for using Hive in JDBC

### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-925

### How should this be tested?
Set the interpreter properties and test it

### Screenshots (if appropriate)

### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No

 ## Hive Interpreter for Apache Zeppelin
 The [Apache Hive](https://hive.apache.org/) ™ data warehouse software facilitates querying and managing large datasets residing in distributed storage. Hive provides a mechanism to project structure onto this data and query the data using a SQL-like language called HiveQL. At the same time this language also allows traditional map/reduce programmers to plug in their custom mappers and reducers when it is inconvenient or inefficient to express this logic in HiveQL.
 
+## Important Notice
+Hive Interpreter will be deprecated and merged into JDBC Interpreter. You can use Hive Interpreter by using JDBC Interpreter with same functionality. See the example below of settings and dependencies.

 ## What is Zeppelin interpreter?
 Zeppelin Interpreter is a plug-in which enables Zeppelin users to use a specific language/data-processing-backend. For example, to use Scala code in Zeppelin, you need `%spark` interpreter.
