While we have an assertion that checks if the number of routing shards is a multiple of the number of shards we need a real hard exception that checks this way earlier. This change adds a check and test that is executed before we create the index. Relates to elastic#26931

There was a problem hiding this comment.
the division then multiplication again looks like you actually want to check that routingNumShards % numTargetShards != 0?
