I attached 2 files which contain the same values

The below query is not doing an implicit cast between a varchar and an integer
{code}
select count(*) from dfs.`cross-sources`.`fewtypes_null.parquet` p
inner join dfs.`cross-sources`.`fewtypes_null.tbl` o
    on p.int_col=o.columns[0];
Query failed: RemoteRpcException: Failure while running fragment., Failure finding function
that runtime code generation expected.  Signature: compare_to_nulls_high( INT:OPTIONAL, VARCHAR:OPTIONAL
) returns INT:REQUIRED [ 08df7d57-c436-4ff8-9a31-48368ba05531 on qa-node190.qa.lab:31010 ]
[ 08df7d57-c436-4ff8-9a31-48368ba05531 on qa-node190.qa.lab:31010 ]
