The Amazon Resource Name (ARN) of the HDFS cluster location to describe.
Reads arguments from the JSON string provided. The JSON string follows the format provided by
--generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value
input, prints a sample input JSON that can be used as an argument for
--cli-input-json. Similarly, if provided
yaml-input it will print a sample input YAML that can be used with
--cli-input-yaml. If provided with the value
output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.
Turn on debug logging.
Override command’s default URL with the given URL.
By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.
Disable automatic pagination.
The formatting style for command output.
A JMESPath query to use in filtering the response data.
Use a specific profile from your credential file.
The region to use. Overrides config/env settings.
Display the version of this tool.
Turn on/off color output.
Do not sign requests. Credentials will not be loaded if this argument is provided.
The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.
The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.
The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.
The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob
fileb:// will always be treated as binary and use the file contents directly regardless of the
cli-binary-format setting. When using
file:// the file contents will need to properly formatted for the configured
Disable cli pager for output.
Automatically prompt for CLI input parameters.
Disable automatically prompt for CLI input parameters.
LocationArn -> (string)
The ARN of the HDFS cluster location.
LocationUri -> (string)
The URI of the HDFS cluster location.
NameNodes -> (list)
The NameNode that manage the HDFS namespace.
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.
Hostname -> (string)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 -> (integer)The port that the NameNode uses to listen to client requests.
BlockSize -> (integer)
The size of the data blocks to write into the HDFS cluster.
ReplicationFactor -> (integer)
The number of DataNodes to replicate the data to when writing to the HDFS cluster.
KmsKeyProviderUri -> (string)
The URI of the HDFS cluster’s Key Management Server (KMS).
QopConfiguration -> (structure)
The Quality of Protection (QOP) configuration specifies the Remote Procedure Call (RPC) and data transfer protection settings configured on the Hadoop Distributed File System (HDFS) cluster.
RpcProtection -> (string)The RPC protection setting configured on the HDFS cluster. This setting corresponds to your
hadoop.rpc.protectionsetting in your
core-site.xmlfile on your Hadoop cluster.
DataTransferProtection -> (string)The data transfer protection setting configured on the HDFS cluster. This setting corresponds to your
dfs.data.transfer.protectionsetting in the
hdfs-site.xmlfile on your Hadoop cluster.
AuthenticationType -> (string)
The type of authentication used to determine the identity of the user.
SimpleUser -> (string)
The user name used to identify the client on the host operating system. This parameter is used if the
AuthenticationTypeis defined as
KerberosPrincipal -> (string)
The Kerberos principal with access to the files and folders on the HDFS cluster. This parameter is used if the
AuthenticationTypeis defined as
AgentArns -> (list)
The ARNs of the agents that are used to connect to the HDFS cluster.
CreationTime -> (timestamp)
The time that the HDFS location was created.
