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:

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.. Fragment 1:4 [Error Id:
