use the following command. CREATE EXTERNAL TABLE ice_t (i int, s string) STORED BY ICEBERG;

Is the source table a JdbcStorageHandler table? Please provide the DDL of the source table, the query used, and any sample data if possible. This information will help us understand the problem better. Also, validate the set -v command, especially configurations like hive.tez.container.size.

HIVE-24552 is back-ported from CDP 7.1.7 and higher versions.

In Hive , __HIVE_DEFAULT_PARTITION__ is a special value used internally to represent: NULL or EMPTY STRINGS in partition column values . Since it's just a string literal in the metadata , you can access it just like any other string in a query. Example : SELECT * FROM your_table WHERE data_dt = '__HIVE_DEFAULT_PARTITION__'; We cannot do WHERE data_dt IS NULL — because NULLs are replaced with __HIVE_DEFAULT_PARTITION__ before being written If you do WHERE length(data_dt) = 26 — it won’t match anything, because partition columns behave differently.

This appears to be a new issue. To help us investigate further, could you please provide the steps to reproduce the problem?

ggangadharan · ‎07-02-2025

Please connect using the Beeline client included with the CDP parcel. Then, check the HiveServer2 (HS2) logs to determine the root cause. Sharing the complete stack trace will also help us identify the issue.

ggangadharan · ‎06-24-2025

Please share the Maven coordinates (groupId and artifactId) for the dependency. On a related note, I recommend we begin a transition from our current HDP dependencies to the latest versions available on the CDP. The HDP dependencies are no longer current, and migrating to CDP will improve our application's stability and supportability.
