Review Comment:
I have found a better way to handle this:
If you check that example, it not only defines the possible values, but also
ensures the casing will be as it is expected. So that, you don't need to call
`toLowerCase()` method when you read the value.
``` java
// setting up execution engine
HIVE_EXECUTION_ENGINE("hive.execution.engine", Runtime.TEZ.toString(),
new StringSet(true, Runtime.MR.toString(),
Runtime.TEZ.toString(),
Runtime.IMPALA.toString()),
// and reading the value
if (HiveConf.getVar(conf,
HiveConf.ConfVars.HIVE_EXECUTION_ENGINE).equals("tez")) {
```
