> The current epsilon used is 1E-6 and its too big it might overflow the
> desiredMaxFileSize. A trivial fix is to lower the epsilon to 2^-52 or even
> 2^-53. An option to consider too is just to shift the jitter to always
> decrement hbase.hregion.max.filesize (MAX_FILESIZE) instead of increase the
> size of the region and having to deal with the round off.
