  • Method Details

    • preExecute

      public org.apache.hadoop.ozone.protocol.proto.OzoneManagerProtocolProtos.OMRequest preExecute(OzoneManager ozoneManager) throws IOException
      Description copied from class: OMClientRequest
      Perform pre-execute steps on a OMRequest. Called from the RPC context, and generates a OMRequest object which has all the information that will be either persisted in RocksDB or returned to the caller once this operation is executed.
      Overrides:
      preExecute in class OMClientRequest
      Returns:
      OMRequest that will be serialized and handed off to Ratis for consensus.
      Throws:
      IOException

    • validateAndUpdateCache

      public OMClientResponse validateAndUpdateCache(OzoneManager ozoneManager, ExecutionContext context)
      Description copied from class: OMClientRequest
      Validate the OMRequest and update the cache. This step should verify that the request can be executed, perform any authorization steps and update the in-memory cache. This step does not persist the changes to the database. To coders and reviewers, CAUTION: Do NOT bring external dependencies into this method, doing so could potentially cause divergence in OM DB states in HA. If you have to, be extremely careful. e.g. Do NOT invoke ACL check inside validateAndUpdateCache, which can use Ranger plugin that relies on external DB.
      Overrides:
      validateAndUpdateCache in class OMKeyAclRequest
      Returns:
      the response that will be returned to the client.

    • blockAddAclWithBucketLayoutFromOldClient

      Validates Add ACL requests. We do not want to allow older clients to create add ACL requests for keys that are present in buckets which use non LEGACY layouts.
      Parameters:
      req - - the request to validate
      ctx - - the validation context
      Returns:
      the validated request
      Throws:
