## What changes were proposed in this pull request?
This patch fixes the problem that `bin\beeline.cmd` pollutes environment variables.
The similar problem is reported and fixed in https://issues.apache.org/jira/browse/SPARK-3943, but `bin\beeline.cmd` seems to be added later.
## How was this patch tested?
manual tests:
I executed the new `bin\beeline.cmd` and confirmed that %SPARK_HOME% doesn't remain in the command prompt.

Tested locally with a Win7 VM. Connected to a Spark SQL Thrift server instance running on Mac OS X with the following command line:
```
bin\beeline.cmd -u jdbc:hive2://10.0.2.2:10000 -n lian
```
