> There was a discussion in HBASE-14388 related to maximum number of log files. It was
an agreement that we should calculate this number in a code but still need to honor user's
setting. 
> Maximum number of log files now is calculated as following:
>  maxLogs = HEAP_SIZE * memstoreRatio * 2/ LogRollSize
