I have docker desktop and I'm trying to do a poc connectivity between ES and Hive.
I have ES container running and hive container.
I'm adding the jar file to hive before creating the external table.
However, it fails with this error.
Unsupported major.minor version 52.0
I read that ES requires JDK8 to run. But mine is running fine and can connect to kibana docker container as well.
ES default java ..15.0.1
Hive java version..1.7.0
Please help.
