> Exception handling inside HbaseObjectWritable needs to be reworked, IMHO. 
> For example:
> At several places inside HbaseObjectWritable.readObject, exceptions are caught and rethrown as I/O Exception (including ClassNotFoundException!). 
> So, if an implementation of readFields method throws a DoNotRetryIOException, HBase still ends up retrying. 
> This problem exists at least in 0.94.12 version of HBase.
