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)
