Method Details

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.

Specified by:

validateAndUpdateCache in class OMClientRequest

Returns:

the response that will be returned to the client.

blockBucketDeleteWithBucketLayoutFromOldClient

public static org.apache.hadoop.ozone.protocol.proto.OzoneManagerProtocolProtos.OMRequest blockBucketDeleteWithBucketLayoutFromOldClient(org.apache.hadoop.ozone.protocol.proto.OzoneManagerProtocolProtos.OMRequest req,
 ValidationContext ctx)
                                                                                                                                  throws IOException

Validates bucket delete requests. Handles the cases where an older client attempts to delete a bucket a new bucket layout. We do not want to allow this to happen, since this would cause the client to be able to delete buckets it cannot understand.

Parameters:

req - - the request to validate

ctx - - the validation context

Returns:

the validated request

Throws:

org.apache.hadoop.ozone.om.exceptions.OMException - if the request is invalid

IOException
