> Online configuration change is a terrific feature for HBase administrators.
> However, when we use this feature to tune compaction thread pool size online,
> it triggered a IllegalArgumentException. The cause is the order of
> setMaximumPoolSize() and setCorePoolSize() of ThreadPoolExecutor: when
> turning parameters bigger, we should setMax first; when turning parameters
> smaller, we need to setCore first. Besides, there is also a copy-code bug in
> merge and split thread pool which I will fix together.
