@Override
protected void configureForRegion(HRegion region) {
super.configureForRegion(region);
Configuration conf = getConf();
HTableDescriptor desc = region.getTableDesc();
if (desc != null) {
this.desiredMaxFileSize = desc.getMaxFileSize();
}
if (this.desiredMaxFileSize <= 0) {
this.desiredMaxFileSize = conf.getLong(HConstants.HREGION_MAX_FILESIZE,
HConstants.DEFAULT_MAX_FILE_SIZE);
}

this.desiredMaxFileSize += (long)(desiredMaxFileSize * (RANDOM.nextFloat() - 0.5D) * jitter);
