[Bug]: Unable to execute hive query #4656
Description
Apache Hop version?
2.8.0
Java version?
java11
Operating system
Windows
What happened?
We are encountering an issue while performing ElasticSearch (ES) synchronization with Hive using the Hop service. The Hive query executes successfully when run directly through Hive, but the same query fails when executed via the Hop service.
This behavior is blocking our workflow, and we need assistance to resolve it.
