Jie Huang commented on HBASE-6312:
----------------------------------
Thanks for those detailed explainations. Yes, you are right. The bigger cache
size makes different of course. The end user somehow can increase the cache
size without tuning that acceptable factor. From the customer's perspective,
it is much easier to configure them than re-compiling the code from time to
time. According to your suggestion, shall we need to make that gap (between
the minimum and acceptable factor) configurable at least?

> 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.
