Description

There are 5 NodeOperationalState s defined at the moment:

  /**
   * Protobuf enum {@code hadoop.hdds.NodeOperationalState}
   */
  public enum NodeOperationalState
      implements com.google.protobuf.ProtocolMessageEnum {
    /**
     * <code>IN_SERVICE = 1;</code>
     */
    IN_SERVICE(0, 1),
    /**
     * <code>DECOMMISSIONING = 2;</code>
     */
    DECOMMISSIONING(1, 2),
    /**
     * <code>DECOMMISSIONED = 3;</code>
     */
    DECOMMISSIONED(2, 3),
    /**
     * <code>ENTERING_MAINTENANCE = 4;</code>
     */
    ENTERING_MAINTENANCE(3, 4),
    /**
     * <code>IN_MAINTENANCE = 5;</code>
     */
    IN_MAINTENANCE(4, 5),
    ;

We should show the Datanode OperationalState in Recon Datanode page as well as it provides valuable information. See the attached screenshots for the result.
