      Work Description: cxorm commented on pull request #164: HDDS-426. Add field modificationTime for Volume and Bucket
URL: https://github.com/apache/hadoop-ozone/pull/164
 
 
   ## What changes were proposed in this pull request?
   We would update the ```modificationTime``` of ```volume``` when
   - ```ozone sh volume create```
   
   - ```ozone sh volume update```
   
   And we would update the ```modificationTime``` of ```bucket``` when
   - ```ozone sh bucket create```
   
   So we focus on these items.
   
   Following disscussion:
   Would we update the ```modificationTime``` of ```volume``` when updating ```key``` or ```bucket``` ?
   Would we update the ```modificationTime``` of ```bucket``` when updating ```key``` ?
   And maybe we could create a JIRA to update the ```modificationTime``` when deleting. (Regarding [HDDS-2416](https://issues.apache.org/jira/browse/HDDS-426
   ))
   
   ## What is the link to the Apache JIRA

   ```TestOMVolumeCreateRequest```
   ```TestOMVolumeSetOwnerRequest```
   ```TestOMVolumeSetQuotaRequest```
   ```TestOMBucketCreateRequest```
