> In HeapMemoryManager#doInit():
> {code}
> globalMemStorePercentMinRange = conf.getFloat(MEMSTORE_SIZE_MIN_RANGE_KEY,
> globalMemStorePercent);
> globalMemStorePercentMaxRange = conf.getFloat(MEMSTORE_SIZE_MAX_RANGE_KEY,
> globalMemStorePercent);
> ...
> if (globalMemStorePercent == globalMemStorePercentMinRange
> && globalMemStorePercent == globalMemStorePercentMaxRange) {
> return false;
> }
> {code}
> If memory tuning is not specified, globalMemStorePercentMinRange and
> globalMemStorePercentMaxRange would carry the value of globalMemStorePercent.
> This would make doInit() exit before checking the threshold for combined
> MemStore and BlockCache percentages.
