"Failed to create DataStorage" error when using Pig with Hadoop

I've been trying to get Pig 0.9.0 to run using Apache Hadoop 0.20.203.0. I've looked high and low over google and mailing lists and even this question: cant run pig with single node hadoop server , but I still can't get Grunt, the Pig shell, to run in a cluster-setup (I can run the prompt fine in local mode, of course).

I've tried the solutions given - recompiling without hadoop, adding the hadoop library and the pig-withouthadoop.jar to my PIG_CLASSPATH variable...nothing works. I just get the error

2011-08-02 10:56:00,709 [main] ERROR org.apache.pig.Main - ERROR 2999: Unexpected internal error. Failed to create DataStorage

Not entirely sure where to go from here. I've seen a few discussions of this on the Apache Pig development website or something (their version control site or whatever) and there were some proposed scripts but I couldn't figure out what his wrapper script was doing or how to use it: https://issues.apache.org/jira/browse/PIG-2183 . Maybe the solution lies in that link?

I'm running a single-node hadoop setup (NOT local mode)...Hadoop works fine.
