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.
