Class SplitLogTask

java.lang.Object

org.apache.hadoop.hbase.SplitLogTask

Direct Known Subclasses:

SplitLogTask.Done, SplitLogTask.Err, SplitLogTask.Owned, SplitLogTask.Resigned, SplitLogTask.Unassigned

@InterfaceAudience.Private
public class SplitLogTask
extends Object

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.
