Subject [jira] [Updated] (TAJO-176) Implement Tajo JDBC Driver
Date Mon, 18 Nov 2013 04:45:20 GMT

     [ https://issues.apache.org/jira/browse/TAJO-176?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Keuntae Park updated TAJO-176:

    Attachment: TAJO-176_2.patch

Thank you for the kind review, Jihoon and Hyunsik

I've uploaded new patch for the comments:

1.  Same way to handle the unimplemented functions
  - Not supported functions throw exception
  - All methods that report supporting capabilities of database functions in DatabaseMetaData
return true or false

2. Correcting wrong exception method
  - Exception specifies the name of the method not supported

3. Pool close
  - Concurrent execution of multiple TajoClients does not matter, because TajoClient does
not release the connection to the pool but just closes it
  -- Please, check the test cases in testMultipleConnections and testMultipleConnectionsSequentialClose
of TestTajoJdbc 

4. Supporting jdk7
  - Implement all the additional methods in jdk7 and replace "@Override annotation" to "//JDK1.7"

5. Unused imports
  - Remove all

6. rebase

> Tajo is required to be integrated with legacy BI or OLAP tools. For this, Tajo should
provide a JDBC driver.
