All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<HdfsNameNode.Builder,HdfsNameNode>
@Generated("software.amazon.awssdk:codegen") public final class HdfsNameNode extends Object implements SdkPojo, Serializable, ToCopyableBuilder<HdfsNameNode.Builder,HdfsNameNode>

The NameNode of the Hadoop Distributed File System (HDFS). The NameNode manages the file system's namespace. The NameNode performs operations such as opening, closing, and renaming files and directories. The NameNode contains the information to map blocks of data to the DataNodes.

  • Method Details

    • hostname

      public final String hostname()

      The hostname of the NameNode in the HDFS cluster. This value is the IP address or Domain Name Service (DNS) name of the NameNode. An agent that's installed on-premises uses this hostname to communicate with the NameNode in the network.

      Returns:
      The hostname of the NameNode in the HDFS cluster. This value is the IP address or Domain Name Service (DNS) name of the NameNode. An agent that's installed on-premises uses this hostname to communicate with the NameNode in the network.

    • port

      public final Integer port()

      The port that the NameNode uses to listen to client requests.

      Returns:
      The port that the NameNode uses to listen to client requests.

    • toBuilder

      public HdfsNameNode.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<HdfsNameNode.Builder,HdfsNameNode>
      Returns:
      a builder for type T

    • builder

      public static HdfsNameNode.Builder builder()

    • serializableBuilderClass

      public static Class<? extends HdfsNameNode.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
