Zhihong Ted Yu commented on HBASE-6312:
---------------------------------------
bq. and block if cache size > hfile.block.cache.size * (1 + acceptable factor)
The default value for acceptable factor would have to change, right ?
> Make BlockCache eviction thresholds configurable

> Some of our customers found that tuning the BlockCache eviction thresholds
> made test results different in their test environment. However, those
> thresholds are not configurable in the current implementation. The only way
> to change those values is to re-compile the HBase source code. We wonder if
> it is possible to make them configurable.
