@gatorsmile @cloud-fan , @wzhfy just give an extra propose, should we
support reset multiple property?
I make a hive test like:
```
hive (temp)> set mapreduce.job.reduces=100;
hive (temp)> set mapreduce.job.reduces;
mapreduce.job.reduces=100
hive (temp)> set mapreduce.job.queuename=root.test;
hive (temp)> set mapreduce.job.queuename;
mapreduce.job.queuename=root.test
hive (temp)> reset mapreduce.job.queuename mapreduce.job.reduces;
hive (temp)> set mapreduce.job.queuename;
mapreduce.job.queuename=root.default
hive (temp)> set mapreduce.job.reduces;
mapreduce.job.reduces=-1
```
