Method Details
-
locationArn
The Amazon Resource Name (ARN) of the source HDFS cluster location.
- Returns:
- The Amazon Resource Name (ARN) of the source HDFS cluster location.
-
subdirectory
A subdirectory in the HDFS cluster. This subdirectory is used to read data from or write data to the HDFS cluster.
- Returns:
- A subdirectory in the HDFS cluster. This subdirectory is used to read data from or write data to the HDFS cluster.
-
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 theisEmpty()
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
The NameNode that manages the HDFS 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. You can use only one NameNode.
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. 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. You can use only one NameNode.
-
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
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
The URI of the HDFS cluster's Key Management Server (KMS).
- Returns:
- The URI of the HDFS cluster's Key Management Server (KMS).
-
qopConfiguration
The Quality of Protection (QOP) configuration specifies the Remote Procedure Call (RPC) and data transfer privacy settings configured on the Hadoop Distributed File System (HDFS) cluster.
- Returns:
- The Quality of Protection (QOP) configuration specifies the Remote Procedure Call (RPC) and data transfer privacy settings configured on the Hadoop Distributed File System (HDFS) cluster.
-
authenticationType
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 returnHdfsAuthenticationType.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available fromauthenticationTypeAsString()
.- Returns:
- The type of authentication used to determine the identity of the user.
- See Also:
-
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 returnHdfsAuthenticationType.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available fromauthenticationTypeAsString()
.- Returns:
- The type of authentication used to determine the identity of the user.
- See Also:
-
simpleUser
The user name used to identify the client on the host operating system.
- Returns:
- The user name used to identify the client on the host operating system.
-
kerberosPrincipal
The Kerberos principal with access to the files and folders on the HDFS cluster.
- Returns:
- The Kerberos principal with access to the files and folders on the HDFS cluster.
-
kerberosKeytab
The Kerberos key table (keytab) that contains mappings between the defined Kerberos principal and the encrypted keys. You can load the keytab from a file by providing the file's address. If you use the CLI, it performs base64 encoding for you. Otherwise, provide the base64-encoded text.
- Returns:
- The Kerberos key table (keytab) that contains mappings between the defined Kerberos principal and the encrypted keys. You can load the keytab from a file by providing the file's address. If you use the CLI, it performs base64 encoding for you. Otherwise, provide the base64-encoded text.
-
kerberosKrb5Conf
The
krb5.conf
file that contains the Kerberos configuration information. You can load thekrb5.conf
file by providing the file's address. If you're using the CLI, it performs the base64 encoding for you. Otherwise, provide the base64-encoded text.- Returns:
- The
krb5.conf
file that contains the Kerberos configuration information. You can load thekrb5.conf
file by providing the file's address. If you're using the CLI, it performs the base64 encoding for you. Otherwise, provide the base64-encoded text.
-
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 theisEmpty()
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
The ARNs of the agents that are used to connect to the 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 agents that are used to connect to the HDFS cluster.

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 interfaceToCopyableBuilder<UpdateLocationHdfsRequest.Builder,

toBuilder
in classDataSyncRequest
- Returns:
- a builder for type T

hashCode
public final int hashCode()- Overrides:

equalsBySdkFields
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 anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
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. -
getValueForField
Description copied from class:SdkRequest
Used to retrieve the value of a field from any class that extendsSdkRequest
. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, theSdkRequest.getValueForField(String, Class)
method will again be available.- Overrides:
getValueForField
in classSdkRequest
- Parameters:
fieldName
- The name of the member to be retrieved.clazz
- The class to cast the returned object to.- Returns:
- Optional containing the casted return value
