InstanceAlreadyExistsException on initializing MiniCluster
Hi everybody,
I'm trying to run some unit tests for a custom LOAD function that use
MiniCluster. I get the following exception when running on pig 0.10.0 :
http://pastebin.com/sNJBgJHC
For pig 0.8.1 I don't get that error. I have no idea how to resolve
this. BTW: I am calling shutdown() on the MiniCluster instance like this:
[...]
private static MiniCluster cluster = MiniCluster.buildCluster();
[...]
@AfterClass
public static void shutdown() {
cluster.shutDown();
}
[...]
I suspect this could be similar to
https://issues.apache.org/jira/browse/HBASE-5711
https://issues.apache.org/jira/browse/HBASE-4709
but I have no idea yet what is the linking piece of code and the bugs
are still open.
The unit test of the pig release (0.10.0) run and also report only
Errors on those tests that use a MiniCluster instance. That seems to me
a show stopper to further development since tests cannot be run reliably...
What can we do to get this running again?

Well, to answer my own question:
I should not put pig.jar but pig-withouthadoop.jar in the CLASSPATH !
Shame on me!
So all our tests are running just fine for now...
Greetings!
