Subject [jira] [Created] (DRILL-4264) Dots in identifier are not escaped correctly
Date Tue, 12 Jan 2016 09:40:39 GMT
Alex created DRILL-4264:
---------------------------

             Summary: Dots in identifier are not escaped correctly
                 Key: DRILL-4264
                 URL: https://issues.apache.org/jira/browse/DRILL-4264
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Codegen
            Reporter: Alex


If you have some json data like this...

    {
      "0.0.1":{
        "version":"0.0.1",
        "date_created":"2014-03-15"
      },
      "0.1.2":{
        "version":"0.1.2",
        "date_created":"2014-05-21"
      }
    }

... 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)
