Hi All,
I have a question here. Scenario: -------------- 1. Cluster is having some blocks and its upgraded. 2. As part of upgrade, in datanode side hardlinks are created for all blocks. 3. Now one of the block is appended with the some more data 4. Do rollback Now what happens for the appended data..? Since blocks are hardlinked, changes on the original file will reflect on the hardlinked file inside previous also. So changes to a appended block after upgrade will not be reverted after rollback. How to handle this case..? Any thoughts..?
