Yin Huai commented on HIVE-5910:
--------------------------------
[~leftylev] Actually, these two are MapReduce configurations. Seems these two
are internally used in Hive. I am not sure if we need to add them to add them
to our conf template.
> In HiveConf, the name of mapred.min.split.size.per.rack is
> MAPREDMINSPLITSIZEPERNODE and the name of mapred.min.split.size.per.node is
> MAPREDMINSPLITSIZEPERRACK

> In HiveConf.java ...
> {code}
> MAPREDMINSPLITSIZEPERNODE("mapred.min.split.size.per.rack", 1L),
> MAPREDMINSPLITSIZEPERRACK("mapred.min.split.size.per.node", 1L),
> {\code}
> Then, in ExecDriver.java ...
> {code}
> if (mWork.getMinSplitSizePerNode() != null) {
> HiveConf.setLongVar(job, HiveConf.ConfVars.MAPREDMINSPLITSIZEPERNODE,
> mWork.getMinSplitSizePerNode().longValue());
> }
> if (mWork.getMinSplitSizePerRack() != null) {
> HiveConf.setLongVar(job, HiveConf.ConfVars.MAPREDMINSPLITSIZEPERRACK,
