Hi everybody,

I am trying to write a test for my pig script (which runs fine on the
command line) registering any jars via the pig.additional.jars property.

I am writing the test with PigUnit as follows:

[...]

Properties props = new Properties();
props.load(new FileInputStream("./testdata/adition.properties"));
if (System.getProperties().containsKey(EXEC_CLUSTER)) {
LOG.info("Using cluster mode");
pig = new PigServer(ExecType.MAPREDUCE, props);
} else {
LOG.info("Using default local mode");
pig = new PigServer(ExecType.LOCAL, props);
}

cluster = new Cluster(pig.getPigContext());
String[] params = {
"data_dir=testdata",
"log_dir=log",
"date=2012-04-21"
};

test = new PigTest("../calcKeywords.pig", params, pig, cluster);
test.override("aggregated_united_logs",
"aggregated_united_logs = ORDER (FOREACH grouped_united_logs GENERATE " +
"group.werbeplatz_id, group.banner_id, group.campaign_id,
group.network, " +
"group.keyword, SUM(united_logs.views), SUM(united_logs.clicks)) BY ASC " +
"werbeplatz_id, banner_id, campaign_id, network, keyword;");
test.assertOutput(new File("./testdata/expected.out"));

[...]

./testdata/adition.properties contains:

pig.import.search.path=/home/schwenk/dev/pig/macros
pig.additional.jars=/home/schwenk/dev/pig/lib/adition.jar:/home/schwenk/dev/pig/lib/adition-test.jar
udf.import.list=com.adition.pig.filtering.string.:com.adition.pig.io.

As far as I could see in the debugger the PigServer registers the
additional jars successfully. Nonetheless the test fails with the
following output, stating that it cannot resolve the import of my custom
LOAD function EscapedPigStorage wich is in adition.jar:

What should I do next?
