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.
