getSizeToCheck

protected long getSizeToCheck(int tableRegionsCount)

覆盖:

getSizeToCheck 在类中 IncreasingToUpperBoundRegionSplitPolicy

返回:

flushSize * 2 if there's exactly one region of the table in question found on this regionserver. Otherwise max file size. This allows a table to spread quickly across servers, while avoiding creating too many regions.
