> Key: HDDS-14337
> URL: https://issues.apache.org/jira/browse/HDDS-14337
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Saketa Chalamchala
> Assignee: Saketa Chalamchala
> Priority: Major
>
> SCM fails to restart after it is first deployed and started near the end of
> the year, say on Dec 31, with the following error due to a Precondition fail
> that check if {code:java} localId > UniqueId.next() {code}
> - `localId`: Uses millisSinceEpoch << Short.SIZE (shift by 16 bits)
> - `UniqueId.next()`: Uses currentTimeMillis << 10 (shift by 10 bits)
> Since UniqueId.next() shifts by fewer bits and includes the current time,
> while localId shifts by more bits but uses a future date (Jan 1st of next
> year), the values can be very close or even inverted, especially near year
> boundaries.
