Gabor Kaszab updated IMPALA-3060:
---------------------------------
Labels: catalog-server complextype impala (was: catalog-server impala)
> Supports IS [NOT] NULL feature for complex types
> ------------------------------------------------
>
> Key: IMPALA-3060
> URL: https://issues.apache.org/jira/browse/IMPALA-3060
> Project: IMPALA
> Issue Type: New Feature
> Components: Frontend
> Affects Versions: Impala 2.3.0, Impala 2.5.0
> Environment: CDH 5.5.1
> Reporter: Petter von Dolwitz
> Priority: Major
> Labels: catalog-server, complextype, impala
>
> The IS NULL / IS NOT NULL operator does not seem to work on structs. This
> functionality is vital when working with "wide" tables.
> Sample query to reproduce (col2 defined as STRUCT<field:STRING>):
> {quote}
> SELECT
> col1
> FROM
> my_table
> WHERE
> col2 IS NOT NULL;
> {quote}
> Output:
> {quote}

> I0223 12:54:45.091451 19314 jni-util.cc:177] java.lang.IllegalStateException:
