Rakesh updated DRILL-5454:
--------------------------
Description:
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.. Fragment 1:4 [Error Id:
1a9b034c-949a-4faa-9185-55d40e4851e7 on uswxapcsd043.ussdnve.baml.com:31010]
(org.apache.drill.exec.exception.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
