Actually, I realize this will continue to be misleading for values greater than 1s. For example 1.9s is almost double what would be shown by formatTime. It matters less for values in the 10s of seconds or higher, but I think it will be very common to have values mostly in the single digit seconds.
We could copy the impl of formatTime here and add ms, or use the existing formatTime and append a ms part, or look for a different "humanize" method/library (as long as it's already a dep)

@bbeaudreault while working on https://issues.apache.org/jira/browse/HBASE-27798 I realized that there's an extra change that I want to make here. These changes would break Though notably, |

admittedly we could clean this up a bit via some sort of loop, but I think the initial implementation suffered from trying to be a little too clever and this both works and is straightforward imo

We should also test that it still works for the old format. We need to make sure it doesn't break if someone deploys the updated client side with old servers or vice versa.

StringUtils#formatTimewill round down millis which can produce misleading error messages on RpcThrottlingExceptions with wait intervals between 0 and 1 second. This PR simply adds support expressing sub-second wait intervals@bbeaudreault
