@vanzin TBH, I wasn't aware of this method while working on this PR. It
seems that `Utils.executeAndGetOutput` doesn't support redirecting stdin of the
forked subprocess. So it's not suitable for `CliSuite`. But it looks neat for
`HiveSparkSubmitSuite` and Hive Thrift server test suites, I'll git it a try.
Thanks for reminding!
