> Currently, RecordReader.getPos() for hbase handler returns always zero and it's not wrong
in the sense that it's not clear how to calculate it(as specified in hbase javadoc).
> But if getPos() returns some meaningful value, it can make percent table sampling in
HIVE-2925 possible to be used, which seemed very useful.
