Subject [jira] [Updated] (DRILL-4264) Dots in identifier are not escaped correctly
Date Tue, 12 Jan 2016 09:43:39 GMT

     [ https://issues.apache.org/jira/browse/DRILL-4264?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex updated DRILL-4264:
------------------------
    Description: 
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)
