I think my hbase is broken

I'm using hbase with Nutch 2.3.1 and getting errors from the 
GeneratorJob step :


GeneratorJob: java.io.IOException: Expecting at least one region.
         at 
org.apache.gora.hbase.store.HBaseStore.getPartitions(HBaseStore.java:398)
         at 
org.apache.gora.mapreduce.GoraInputFormat.getSplits(GoraInputFormat.java:94)


I think this means hbase needs it's gora-based schema reapplying or 
something ? How does one do that ? Using a fresh hbase install doesn't 
seem to have helped.
