> Repro:
> {code:java}
> CREATE TABLE IF NOT EXISTS tmp_ice
> (id int, date_string_col string)
> PARTITIONED BY SPEC (date_string_col)
> STORED AS ICEBERG;
> insert into tmp_ice select id, date_string_col from functional_parquet.alltypes;
> select * from tmp_ice where date_string_col = "09/01/09";
> {code}
> This select gives zero rows.
> However, I create the table partitioned by another col, e.g. 'id' then the very same select gives 10 rows as expected.
> The issue may be somewhere here where we split the path by '/' char:
