[jira] [Created] (METAMODEL-160) Apache Hive support w. MetaModel-jdbc module

Kasper Sørensen created METAMODEL-160:
-----------------------------------------

             Summary: Apache Hive support w. MetaModel-jdbc module
                 Key: METAMODEL-160
                 URL: https://issues.apache.org/jira/browse/METAMODEL-160
             Project: Apache MetaModel
          Issue Type: Improvement
            Reporter: Kasper Sørensen
            Assignee: Kasper Sørensen


Connecting to Apache Hive is pretty straight forward via vanilla JDBC, but a few things are different, especially regarding executing updates:

 * The type system has some specifics, such as the integer type being named INT.
 * The database does not support explicit calls to commit or rollback. It is always in autocommit mode because it doesn't support transactions anyway.

For just queries it seems that it more or less already works. But we should also have an integration test so that we can track it's support and expand with tests should any Hive-specific support issues appear.
