> Run createFakeDirIfShould outside the lock to prevent OM stuck

> Key: HDDS-14841
> URL: https://issues.apache.org/jira/browse/HDDS-14841
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Ivan Andika
> Assignee: Ivan Andika
> Priority: Major
> Labels: pull-request-available
>
> We have encountered incidents caused by createFakeDirIfShould in
> getFileStatus since createFakeDirIfShould creates a RocksDB iterator and it
> might take a long time when the keyTable has a lot of tombstones. This
> causes OM to be stuck since writes on the same bucket will be held, which in
> turns held all the pending write transactions in OM Ratis applier.
> Let's move createFakeDirIfShould outside of the lock to prevent this. There
> is some tradeoff in terms of consistency, but since createFakeDirIfShould
> should not be the normal case, we can contend with this.
