Yiqun Lin commented on HDFS-11951:
----------------------------------
[~cheersyang], I am thinking this corner case will not be happen actually.
{{BucketManagerImpl}} holds the readLock before doing list buckets operation,
and {{ReadLock}}, {{WriteLock}} are mutual exclusive. So during this time, the
delete key operations should not be happened since delete operation will
require the write lock.
Correct me if I am wrong, :).

> In the discussions in HDFS-11779, there might be a corner case we running
> into the situation that some key are deleted while we are listing them. For
> example
> 1. A list call is made say from key1 to key100 is returned.
> 2. Someone deletes the key100
> 3. A list continue call is made with startKey=key100.
> We need to investigate this case and make sure this is properly handled in
> ozone. See more discussion from [here |
