Create cache miss scenario in HBase with HDP 2.6.5


I have tried several scenarios to generate cache miss in HBase with HDP 2.6.5. Different steps I followed include:

 1) putting value in HBase using put command and fetching using get command.

 2) putting value in HBase with put command , flushing and the trying to fetch the data. 

None of this creates cache misses. Infact the hits and hits caching keeps increasing by multiple counts during flushing. Misses and misses caching always remains zero. Why is this  behaviour occurring? What is the difference between misses and misses caching and hits and hits caching?

I will attach the screen shots of region server logs.
