> Currently if we are reading vertex/edge data from multiple tables, and we only want to read a fraction of data (with giraph.inputSplitSamplePercent conf option), we'll always get the first inputSplitSamplePercent of the input slits. We should instead use a random sample of input splits so testing on sample of data would look closer to actual full data run.
