Ted Yu updated HBASE-13989:
---------------------------
Description:
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.
