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.
