-------------------------------------------------------
Yes, it's string type for all elements (For the one use case I have) (i.e. when
the element is created it is of the form ("x1", "x2", ...). I have also edited
my JIRA with a note to explain the same.

> I have a parquet file with an array column, when I use the function
> 'REPEATED_COUNT' in select column it works fine, but when used in where
> clause I get an error:
> org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR:
> SchemaChangeException: Failure while trying to materialize incoming schema.
> Errors: Error in expression at index 2. Error: Missing function
> implementation: [repeated_count(INT-OPTIONAL)]. Full expression: null..

> Note: The query is reading data from a parquet file. This file was generated
> using a CTAS expression from a CSV file, and the array column was generated
> using CONVERT_FROM(colName, 'JSON'). The column has the string in the correct
> format (["x1", "x2"]). Also the count comes out correct when I use the
> REPEATED_COUNT(arrayCol) in select column, it's just failing in the where
> clause
