             Summary: two client parallel perform commit with Hsync can cause dataloss
                 Key: HDDS-9176
                 URL: https://issues.apache.org/jira/browse/HDDS-9176
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Sumit Agrawal


2 client performs commit with hsync feature,
 * client 1 perform commit with Hsync with x block, key will be added in keyTable
 * client 2 perform commit with Hsync with y block,
 ** will overwrite previous key,
 ** quota can be issue as previous key of client 1 is used to identify space usages delta
 * client 1 perform final commit, will be treated as overwrite and remove blocks of client 2 data
 * client 2 perform final commit, this will overwrite and remove blocks of client 1 data

So in above flow, it can cause dataloss and quota will be not be counted properly for space usages.
