There was a problem hiding this comment.
this whole if clause could then be changed to something similar to
checkpoints.compute(shard.getShardRouting().getId(), (shardId, cp) -> (cp == null) ? globalCheckpoint : Math.max(cp, globalCheckPoint))

Take the max if global checkpoints mismatch instead of throwing an exception. It turned out global
checkpoints can mismatch by design
fixes #48379
Severity: checkpoint creation can fail due to this issue in rare cases, however checkpoint creation is retried
