--------------------------------

FAILURE: Integrated in HBase-1.2 #39 (See [https://builds.apache.org/job/HBase-1.2/39/])
HBASE-13989 Threshold for combined MemStore and BlockCache percentages is not checked (tedyu:

> 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.
