Guangxu Cheng commented on HBASE-17951:
---------------------------------------
Yes, LongAdder is faster than AtomicLong.
I want to use incrementAndGet, but LongAdder is not implemented.
If we use LongAdder, can we do like this?
{code}
long tmpBlockedRequestsCount;
synchronized (blockedRequestsCount) {
blockedRequestsCount.increment();
tmpBlockedRequestsCount = getBlockedRequestsCount();
}
{code}
Do you have any suggestions? Thanks. [~anoop.hbase]

> We throw RegionTooBusyException in HRegion#checkResources if above memstore
> limit. On the server side，we just increment the value of blockedRequestsCount
> and do not print the region's information.
> I think we should also print the region's information in server-side, so that
> we can easily find the busy regions.
