Lars Hofhansl updated HBASE-6456:
---------------------------------
Affects Version/s: (was: 0.94.2)
I see. I removed 0.94.2 as affected version then.
This is probably due to the modularization of HBase in 0.96 then, there will
likely be other classes missing.

> We could add Bytes.class into dependency Jars of the MapReduce job.
