Examples of org.apache.hadoop.hbase.SplitLogTask$Unassigned

org.apache.hadoop.hbase.SplitLogTask
State of a WAL log split during distributed splitting. State is kept up in zookeeper. Encapsulates protobuf serialization/deserialization so we don't leak generated pb outside of this class. Used by regionserver and master packages.
