IMPORTING

Required arguments:

iv_locationarn TYPE /AWS1/DSYLOCATIONARN /AWS1/DSYLOCATIONARN

The Amazon Resource Name (ARN) of the source HDFS cluster location.

Optional arguments:

iv_subdirectory TYPE /AWS1/DSYHDFSSUBDIRECTORY /AWS1/DSYHDFSSUBDIRECTORY

A subdirectory in the HDFS cluster. This subdirectory is used to read data from or write data to the HDFS cluster.

it_namenodes TYPE /AWS1/CL_DSYHDFSNAMENODE=>TT_HDFSNAMENODELIST TT_HDFSNAMENODELIST

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.

iv_blocksize TYPE /AWS1/DSYHDFSBLOCKSIZE /AWS1/DSYHDFSBLOCKSIZE

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

iv_replicationfactor TYPE /AWS1/DSYHDFSREPLICATIONFACTOR /AWS1/DSYHDFSREPLICATIONFACTOR

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

iv_kmskeyprovideruri TYPE /AWS1/DSYKMSKEYPROVIDERURI /AWS1/DSYKMSKEYPROVIDERURI

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

io_qopconfiguration TYPE REF TO /AWS1/CL_DSYQOPCONFIGURATION /AWS1/CL_DSYQOPCONFIGURATION

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.

iv_authenticationtype TYPE /AWS1/DSYHDFSAUTHNTCTNTYPE /AWS1/DSYHDFSAUTHNTCTNTYPE

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

iv_simpleuser TYPE /AWS1/DSYHDFSUSER /AWS1/DSYHDFSUSER

The user name used to identify the client on the host operating system.

iv_kerberosprincipal TYPE /AWS1/DSYKERBEROSPRINCIPAL /AWS1/DSYKERBEROSPRINCIPAL

The Kerberos principal with access to the files and folders on the HDFS cluster.

iv_kerberoskeytab TYPE /AWS1/DSYKERBEROSKEYTABFILE /AWS1/DSYKERBEROSKEYTABFILE

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.

iv_kerberoskrb5conf TYPE /AWS1/DSYKERBEROSKRB5CONFFILE /AWS1/DSYKERBEROSKRB5CONFFILE

The krb5.conf file that contains the Kerberos configuration information. You can load the krb5.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.

it_agentarns TYPE /AWS1/CL_DSYAGENTARNLIST_W=>TT_AGENTARNLIST TT_AGENTARNLIST

The Amazon Resource Names (ARNs) of the DataSync agents that can connect to your HDFS cluster.

RETURNING

oo_output TYPE REF TO /aws1/cl_dsyupdatelochdfsrsp /AWS1/CL_DSYUPDATELOCHDFSRSP

Syntax Example

This is an example of the syntax for calling the method. It includes every possible argument and initializes every possible value. The data provided is not necessarily semantically accurate (for example the value "string" may be provided for something that is intended to be an instance ID, or in some cases two arguments may be mutually exclusive). The syntax shows the ABAP syntax for creating the various data structures.

DATA(lo_result) = lo_client->updatelocationhdfs(
  io_qopconfiguration = new /aws1/cl_dsyqopconfiguration(
    iv_datatransferprotection = |string|
    iv_rpcprotection = |string|
  )
  it_agentarns = VALUE /aws1/cl_dsyagentarnlist_w=>tt_agentarnlist(
    ( new /aws1/cl_dsyagentarnlist_w( |string| ) )
  )
  it_namenodes = VALUE /aws1/cl_dsyhdfsnamenode=>tt_hdfsnamenodelist(
    (
      new /aws1/cl_dsyhdfsnamenode(
        iv_hostname = |string|
        iv_port = 123
      )
    )
  )
  iv_authenticationtype = |string|
  iv_blocksize = 123
  iv_kerberoskeytab = '5347567362473873563239796247513D'
  iv_kerberoskrb5conf = '5347567362473873563239796247513D'

  iv_kmskeyprovideruri = |string|
  iv_locationarn = |string|
  iv_replicationfactor = 123

).

This is an example of reading all possible response values
