John Sichi commented on HIVE-1335:
----------------------------------
http://ant.apache.org/ivy/history/latest-milestone/tutorial/start.html
So, in metastore/ivy.xml, you can declare a dependency like this:
<dependency org="commons-dbcp" name="commons-dbcp" rev="1.2.2"/>
Search here for the other modules:
http://mvnrepository.com/
Then metastore/build.xml needs to invoke ivy-retrieve from some target, maybe
compile?

> Currently each Data Nucleus operation disconnects and reconnects to the
> MetaStore over jdbc. Queries fail to even explain properly in cases where a
> table has many partitions. This is fixed by enabling one parameter and
> including several jars.
