> HDDS-8765 uses Guava's [Striped|https://guava.dev/releases/19.0/api/docs/com/google/common/util/concurrent/Striped.html] to implement striped locks in OM. For now, Striped doesn't allow creating striped locks with a custom fairness order. Details are in [this PR|https://github.com/apache/ozone/pull/4885].
> This ticket is reserved for a simple implementation of Striped in our own code base to allow the creation of striped locks with custom fairness.
