Reid Chan updated HBASE-14743: ------------------------------ Attachment: HBASE-14743.008.patch "How many decided to expand memstore" √ "How many decided to expand block cache" √ "How many decided to do nothing" √ plus: How many times that the heap occupancy is above the low watermark. This patch improves the documentation according to reviews, removes duplicated metrics. It Also provides histograms for those factors that have impact on the tuner result: cacheEvictedCount, cacheMissCount, blockedFlushCount, unblockedFlushCount, curMemStoreUsed and curBlockCacheUsed. In particular, the histograms for curMemStoreUsed and curBlockCacheUsed are shown in two aspects. One is in size which is more straightforward, the other is in percentage which is more statistical.
