> Key: MAHOUT-431

> Project: Mahout

> I'm trying to use the complementary Bayes classifier and store the model in
> HBase (using BayesParameters.set("dataSource", "hbase")). When I run the MR
> jobs using CBayesDrvier, I get a NullPointerException in
> CBayesThetaNormalizerReducer at line 92:
> hBconf.set(new HBaseConfiguration(job));
> 'hBconf' is a ThreadLocal<HBaseConfiguration> field and it looks like it has
> not been initialized. I initialized it and the model built successfully. I
> observed the same bug in the 0.3 release and in 0.4-SNAPSHOT. I'll attach a
> patch that initializes the field.
