Known Issues in Apache Hive
This topic describes known issues and workarounds for Hive in this release of Cloudera Runtime.
- CDPD-21365: Performing a drop catalog operation drops the catalog from the CTLGS table. The DBS table has a foreign key reference on CTLGS for CTLG_NAME. Because of this, the DBS table is locked and creates a deadlock.
- You must create an index in the DBS table on CTLG_NAME: CREATE INDEX CTLG_NAME_DBS ON DBS(CTLG_NAME);.
- OPSAPS-60546: Upgrading from CDH to Cloudera Runtime 7, the Hive Java Heap Size does not propagate and defaults to 2GB.
- Manually reconfigure Hive Java Heap Size after upgrade.
- OPSAPS-54299 Installing Hive on Tez and HMS in the incorrect order causes HiveServer failure
- You need to install Hive on Tez and HMS in the correct order; otherwise, HiveServer fails. You need to install additional HiveServer roles to Hive on Tez, not the Hive service; otherwise, HiveServer fails.
- CDPD-23041: DROP TABLE on a table having an index does not work
- If you migrate a Hive table to CDP having an index, DROP TABLE
does not drop the table. Hive no longer supports indexes (HIVE-18448). A foreign key constraint on the indexed table prevents dropping the
table. Attempting to drop such a table results in the following error:
java.sql.BatchUpdateException: Cannot delete or update a parent row: a foreign key constraint fails ("hive"."IDXS", CONSTRAINT "IDXS_FK1" FOREIGN KEY ("ORIG_TBL_ID") REFERENCES "TBLS ("TBL_ID"))
- CDPD-12301: Spark Hive Streaming using HWC fails
- Spark Hive Streaming using HWC can fail throwing a java.lang.NoSuchMethodException message.
- HiveServer Web UI displays incorrect data
- If you enabled auto-TLS for TLS encryption, the HiveServer2 Web UI does not display the correct data in the following tables: Active Sessions, Open Queries, Last Max n Closed Queries
- CDPD-11890: Hive on Tez cannot run certain queries on tables stored in encryption zones
- This problem occurs when the Hadoop Key Management Server (KMS) connection is SSL-encrypted and a self signed certificate is used. SSLHandshakeException might appear in Hive logs.
Technical Service Bulletins
- TSB 2021-459: Renaming managed (ACID) table shows empty records
- Renaming an ACID (managed) table using ALTER TABLE <table name> RENAME causes empty
records in the table. Also, the location of the new table after renaming points to the
location of the old table before renaming. This can cause correctness issues, for
example:
create table abc (id int); insert into abc values (1); rename table abc to def; create table abc (id int); // should be empty insert into abc values (2); select * from abc ; // returns 1 and 2, the new and the old results

- TSB 2021-480/1: Hive produces incorrect query results when skipping a header in a binary file
- In CDP, setting the table property
skip.header.line.count
to greater than 0 in a table stored in a binary format, such as Parquet, can cause incorrect query results. The skip header property is intended for use with Text files and typically used with CSV files. The issue is not present when you run the query on a Text file that sets the skip header property to 1 or greater. - Upstream JIRA

- TSB 2021-480/2: Hive ignores the property to skip a header or footer in a compressed file
- In CDP, setting the table properties
skip.header.line.count
andskip.footer.line.count
to greater than 0 in a table stored in a compressed format, such as bzip2, can cause incorrect results from SELECT * or SELECT COUNT ( * ) queries. - Upstream JIRA

- TSB 2021-482: Race condition in subdirectory delete/rename causes hive jobs to fail
- Multiple threads try to perform a rename operation on s3. One of the threads fails to perform a rename operation, causing an error. Hive logs will report "HiveException: Error moving ..." and the log will contain an error line starting with " Exception when loading partition " -all paths listed with s3a:// prefixes.

- TSB 2021-501: JOIN queries return wrong result for join keys with large size in Hive
- JOIN queries return wrong results when performing joins on large size keys (larger than 255 bytes). This happens when the fast hash table join algorithm is enabled, which is enabled by default.

- TSB 2021-518: Incorrect results returned when joining two tables with different bucketing versions
- Incorrect results are returned when joining two tables with different bucketing versions, and with the following Hive configurations: set hive.auto.convert.join = false and set mapreduce.job.reduces = any custom value.

- TSB 2021-524: Intermittent data duplication if direct insert enabled
- If direct insert is enabled, data is written directly to the final location with an
attemptId. At the end of the insert operation, all data written before the final attempt
should be deleted. However due to a bug in HIVE-21164, this does not happen.
Example: Data is written to the final location with attemptId=0, but this task fails. Hive tries the task again and writes data to the final location with attemptId=1. At the end of the insert, Hive should remove all the files with attemptId=0, but it does not.

- TSB 2022-526: A Hive query may produce wrong results for some vectorized built-in functions with compound expression in PARTITION BY or ORDER BY clause
- Vectorized functions with PARTITION BY and/or ORDER BY clauses where the partition or
order by expression is compound (example: cast string to integer) and not just a simple
column reference may be broken.The query may fail or output wrong results, depending on the compound expression. For example:
- Cast integer to string results in query failure with a NullPointerExpression
- Cast string to integer outputs wrong results

- TSB 2023-627: IN/OR predicate on binary column returns wrong result
- An IN or an OR predicate involving a binary datatype column may
produce wrong results. The OR predicate is converted to an IN due to the setting
hive.optimize.point.lookup
which is true by default. Only binary data types are affected by this issue. See https://issues.apache.org/jira/browse/HIVE-26235 for example queries which may be affected. - Upstream JIRA
