Duo Zhang commented on HBASE-22761:
-----------------------------------
How could step 8 happen? Have you seen this in real production, i.e, the first
flush on a stream is broken but the second one is succeeded?
If this could happen, then we also need to check epoch in syncComplete method
then. You can see the code in syncFailed, we could apply the this same in
syncComplete. But I still wonder whether this could happen in real world.
Thanks.
