Jingcheng Du commented on HBASE-14152:
--------------------------------------
Right, this is not atomic, and cannot avoid the race condition.
I think metrics is a rough statistics, few race condition is allowed?
HBase has some similar usages in HStore where the volatile variables are used.
I think it made a tradeoff between the accuracy and speed?
