----------------------------------
Summary: Hive Parallel Tasks - Hive Configuration
ConcurrentModificationException
Key: HIVE-20665
URL: https://issues.apache.org/jira/browse/HIVE-20665
Project: Hive
Issue Type: Bug
Components: HiveServer2
Affects Versions: 3.1.0, 2.3.2, 4.0.0
Reporter: BELUGA BEHR
When parallel tasks are enabled in Hive, all of the resulting queries share the
same Hive configuration. This is problematic as each query will modify the
same {{HiveConf}} object with things like query ID and query text. This will
overwrite each other and cause {{ConcurrentModificationException}} issues.
