Ethan Rose updated HDDS-13083:
------------------------------
Status: Patch Available (was: Open)
> Handle cases where block deletion generates tree file before scanner
> --------------------------------------------------------------------
>
> Key: HDDS-13083
> URL: https://issues.apache.org/jira/browse/HDDS-13083
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Ethan Rose
> Assignee: Ethan Rose
> Priority: Major
>
> In a cluster upgraded to the first version supporting reconciliation, it is
> likely that block deletion will reach many closed containers before the
> scanner does, which will generate the checksum file with a block delete list
> but no merkle tree. We need to make sure our file parsing code does not raise
> errors if it encounters a checksum file with no merkle tree. We also cannot
> use file existence to indicate the presence of checksum info like
> [here|https://github.com/apache/ozone/blob/56e7ed4824f18f8d681b3570904ac8253d9d375f/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/keyvalue/KeyValueHandler.java#L1394].
