 * This class intends to test a UDF that has some classes that the Catalog's
 * class loader can't resolve. We import the class NumberParseException from
 * Google's phone number library that won't be shaded with the UDF jar. The
 * Catalog should gracefully handle this situation by ignoring the load of
 * Java UDF that references this jar.
 *
 * The jar for this file can be built by running "mvn clean package" in
 * tests/test-hive-udfs. This is run in testdata/bin/create-load-data.sh, and
 * copied to HDFS in testdata/bin/copy-udfs-uda.sh.
