Hi, I am running hbase 0.94.3 and I am trying to understand the LRU cache stats here:
LRU Stats: total=428.75 MB, free=4.05 GB, max=4.46 GB, blocks=35961, accesses=23808283, hits=23098837, hitRatio=97.02%, cachingAccesses=23135166, cachingHits=23066278, cachingHitsRatio=99.70%, *evictions=0, evicted=33211* * * I don't understanding why the number of evictions is 0 - which means that the number of eviction thread runs is 0, AFAIK. Also, I see that 30K blocks were evicted - how is that possible ? I have set the hfile evict on close to the default value - which is false - so blocks should not be evicted when hfiles are closed. Where are the evicted blocks coming from when the block is mostly empty and no eviction runs have occured. Thanks Varun
