Class DescribeLocationHdfsResponse

    • Method Detail

      • locationArn

        public final String locationArn()

        The ARN of the HDFS location.

        Returns:
        The ARN of the HDFS location.

      • locationUri

        public final String locationUri()

        The URI of the HDFS location.

        Returns:
        The URI of the HDFS location.

      • hasNameNodes

        public final boolean hasNameNodes()
        For responses, this returns true if the service returned a value for the NameNodes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • nameNodes

        public final List<HdfsNameNode> nameNodes()

        The NameNode that manages the HDFS namespace.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasNameNodes() method.

        Returns:
        The NameNode that manages the HDFS namespace.

      • blockSize

        public final Integer blockSize()

        The size of the data blocks to write into the HDFS cluster.

        Returns:
        The size of the data blocks to write into the HDFS cluster.

      • replicationFactor

        public final Integer replicationFactor()

        The number of DataNodes to replicate the data to when writing to the HDFS cluster.

        Returns:
        The number of DataNodes to replicate the data to when writing to the HDFS cluster.

      • kmsKeyProviderUri

        public final String kmsKeyProviderUri()

        The URI of the HDFS cluster's Key Management Server (KMS).

        Returns:
        The URI of the HDFS cluster's Key Management Server (KMS).

      • qopConfiguration

        public final QopConfiguration qopConfiguration()

        The Quality of Protection (QOP) configuration, which specifies the Remote Procedure Call (RPC) and data transfer protection settings configured on the HDFS cluster.

        Returns:
        The Quality of Protection (QOP) configuration, which specifies the Remote Procedure Call (RPC) and data transfer protection settings configured on the HDFS cluster.

      • authenticationTypeAsString

        public final String authenticationTypeAsString()

        The type of authentication used to determine the identity of the user.

        If the service returns an enum value that is not available in the current SDK version, authenticationType will return HdfsAuthenticationType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from authenticationTypeAsString().

        Returns:
        The type of authentication used to determine the identity of the user.
        See Also:
        HdfsAuthenticationType

      • simpleUser

        public final String simpleUser()

        The user name to identify the client on the host operating system. This parameter is used if the AuthenticationType is defined as SIMPLE.

        Returns:
        The user name to identify the client on the host operating system. This parameter is used if the AuthenticationType is defined as SIMPLE.

      • kerberosPrincipal

        public final String kerberosPrincipal()

        The Kerberos principal with access to the files and folders on the HDFS cluster. This parameter is used if the AuthenticationType is defined as KERBEROS.

        Returns:
        The Kerberos principal with access to the files and folders on the HDFS cluster. This parameter is used if the AuthenticationType is defined as KERBEROS.

      • hasAgentArns

        public final boolean hasAgentArns()
        For responses, this returns true if the service returned a value for the AgentArns property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • agentArns

        public final List<String> agentArns()

        The ARNs of the DataSync agents that can connect with your HDFS cluster.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAgentArns() method.

        Returns:
        The ARNs of the DataSync agents that can connect with your HDFS cluster.

      • creationTime

        public final Instant creationTime()

        The time that the HDFS location was created.

        Returns:
        The time that the HDFS location was created.

      • 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
