Try to SELECT values from druid external table with WHERE clause.
Create external table

```
CREATE EXTERNAL TABLE IF NOT EXISTS druid_wikiticker
STORED BY 'org.apache.hadoop.hive.druid.DruidStorageHandler'
TBLPROPERTIES ("druid.datasource" = "wikiticker");
```

and try select values from external table

```

SELECT `__time`, `namespace`
FROM druid_wikiticker
WHERE `namespace` = 'Main'
```

[Waiting] 

All values are selected
[Reality]


Column by WHERE clause is null

Error stay here:

Where i use 'GROUP BY' OR 'TRIM' Output has another value and return all data what i need. When i execute in druid query, vc0 return null. After i change "expression":"`namespace`" and execute query in druid, druid return real values.
