Patrick Hunt commented on HIVE-2315:
------------------------------------
Mythili, please take a look at the HIVE-2315_part2.patch file I just attached
to this jira. The existing tests were not strongly verifying that "select *
from table" was returning the partition column as part of the result set. I
updated the test to do so. However subsequently the test is still passing (I
verified in the debugger that this code is being executed).
Please take a look at this test:
org.apache.hadoop.hive.jdbc.TestJdbcDriver.doTestSelectAll(String, int, int)
called from here:
org.apache.hadoop.hive.jdbc.TestJdbcDriver.testSelectAllPartioned()
So, afaict, we are returning the partition column as part of the result set.
(I'm also seeing this in squirrel as I mentioned).
Can you take a look at your setup again? Perhaps there is another issue
somewhere in the Hive JDBC driver that's causing DBVizualizer to display this
problem while Squirrel is fine?

> getColumns() method of DatabaseMetadata for HIVE JDBC Driver does not return
> the partition column names. Where as from HIVE CLI, if you do a 'describe
> tablename' you get all columns including the partition columns. It would be
> nice if getColumns() method returns all columns.
