    [ https://issues.apache.org/jira/browse/HIVE-4573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13729892#comment-13729892
] 

Gunther Hagleitner commented on HIVE-4573:
------------------------------------------

[~appodictic], [~thejas], [~prasadm] - If I understand this correctly this patch is needed
as is and I am planning to commit in a few hours. The discussion on default, deprecation etc
is happening on HIVE-4998. Speak up in the next couple of hours if you disagree.

> The getTables jdbc function no longer returns information when using normal JDBC table
types like TABLE or VIEW. You must now use a more specific type such as MANAGED_TABLE or VIRTUAL_VIEW.
An example application that will fail to return results against 0.10 is below, works without
issue in 0.9. In my 0.10 test I used HS2.

>       e.printStackTrace();
>       System.exit(1);
>     }
>     Connection con = DriverManager.getConnection("jdbc:hive2://hostname:10000/default");
>     DatabaseMetaData dbmd = con.getMetaData();
>     String[] types = {"TABLE"};
>     ResultSet rs = dbmd.getTables(null, null, "%", types);
>       while (rs.next()) {
>         System.out.println(rs.getString("TABLE_NAME"));
>       }
>     }
>   }
