[jira] [Commented] (IMPALA-12612) Enable EXPAND_COMPLEX_TYPES for Iceberg Metadata tables
[ https://issues.apache.org/jira/browse/IMPALA-12612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17833646#comment-17833646 ]

IMPALA-12899: Temporary workaround for BINARY in complex types
The BINARY type is currently not supported inside complex types and a
cross-component decision is probably needed to support it (see
IMPALA-11491). We would like to enable EXPAND_COMPLEX_TYPES for Iceberg
metadata tables (IMPALA-12612), which requires that queries with BINARY
inside complex types don't fail. Enabling EXPAND_COMPLEX_TYPES is a more
prioritised issue than IMPALA-11491, so we have come up with a
temporary solution.
This change NULLs out BINARY values in complex types coming from Iceberg
metadata tables and logs a warning.
BINARYs in complex types from regular tables are not affected by this
change.
Testing:
- Added test queries in iceberg-metadata-tables.test.
