• What is the cause and solution for SAP error message RSDA_HDP200 - No authorization to browse HDFS ?

  The SAP error message RSDA_HDP200: No authorization to browse HDFS typically occurs when a user attempts to access Hadoop Distributed File System (HDFS) through SAP Data Services or SAP BW/4HANA and does not have the necessary permissions to do so. This error is related to the integration of SAP systems with Hadoop environments.
  Cause:
  The primary cause of this error is a lack of proper authorization for the user account trying to access HDFS. This can happen due to several reasons:
  
  User Permissions: The user does not have the required permissions to browse or access the HDFS directories or files.
  Hadoop Configuration: The Hadoop cluster may not be configured to allow access from the SAP system.
  Kerberos Authentication: If the Hadoop cluster is secured with Kerberos, the user may not have a valid Kerberos ticket or may not be properly authenticated.
  
  Solution:
  To resolve the RSDA_HDP200 error, you can take the following steps:
  
  
  Check User Permissions:
  
  Ensure that the user account has the necessary permissions to access the HDFS directories and files. You may need to grant read or execute permissions on the relevant directories.
  Use Hadoop commands (like hdfs dfs -ls /path/to/directory) to verify the permissions.
  
  
  
  Hadoop Configuration:
  
  Verify that the Hadoop cluster is configured to allow connections from the SAP system. Check the core-site.xml and hdfs-site.xml configurations for any restrictions.
  Ensure that the SAP system is correctly configured to connect to the Hadoop cluster.
  
  
  
  Kerberos Authentication:
  
  If your Hadoop cluster uses Kerberos for authentication, ensure that the user has a valid Kerberos ticket. You can obtain a ticket using the kinit command.
  Check the configuration of the SAP system to ensure it is set up for Kerberos authentication if required.
  
  
  
  SAP System Configuration:
  
  Ensure that the SAP Data Services or BW/4HANA is properly configured to connect to the Hadoop environment. This includes setting up the correct connection parameters and ensuring that the necessary libraries are available.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for specific instructions on configuring access to HDFS, as well as any prerequisites that may be required.
  
  
  
  Contact Administrator:
  
  If you are not able to resolve the issue, contact your system administrator or the team responsible for managing the Hadoop cluster for further assistance.
