I reverted these changes. Also, I commented out the test where this code is
used with the map fields.

> Project: Apache Drill
> Issue Type: Improvement

> If you have some json data like this...
> {code:javascript}
> {
> "0.0.1":{
> "version":"0.0.1",
> "date_created":"2014-03-15"
> },
> "0.1.2":{
> "version":"0.1.2",
> "date_created":"2014-05-21"
> }
> }
> {code}
> ... there is no way to select any of the rows since their identifiers contain
> dots and when trying to select them, Drill throws the following error:
> Error: SYSTEM ERROR: UnsupportedOperationException: Unhandled field reference
> "0.0.1"; a field reference identifier must not have the form of a qualified
> name
> This must be fixed since there are many json data files containing dots in
> some of the keys (e.g. when specifying version numbers etc)
