Hive + JDK7: datanucleus issues

[Chris Drome <cd...@yahoo-inc.com>]

Hi,

I'm looking into making Hive work with JDK7.

In the process I ran into some issues related to datanucleus  and was hoping for some help.

Hive currently builds with datanucleus-2.0.3 which pulls in asm-3.1.
Building against JDK7 causes the error described in:

http://www.datanucleus.org/servlet/jira/browse/NUCENHANCER-81

It seems that asm must be >3.2 in order to work with JDK7.

So I tried building hive against datanucleus-3.1.0-release which pulls in asm-4.0.

Although this seems to resolve the error mentioned above, it results in various other JDO exceptions on the unit tests.

Has anyone had experience upgrading datanucleus in the context of hive?

One thing to be concerned about is that it seems there are no plans for making datanucleus work with JDK7.

Any comments or suggestions are welcome.

Thanks,

chris
