Hive metastore depends on derby 10.10.2, and we package derby 10.12.1 when
building Spark, so at last we are using derby 10.12.1 when Spark uses local
hive metastore.
However this is a tricky approach, e.g. it doesn't work for SBT. When you
build Spark with SBT, you are still using derby 10.10.2. It's probably the
reason why the test failed on jenkins.
Here I explicitly add the derby dependency to the hive module, to overwrite
the default derby 10.10.2 dependency.
