public boolean isResigned() {
    return this.state == ZooKeeperProtos.SplitLogTask.State.RESIGNED;
  }
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.
