The hive does not work during installation

Question

I get the following error in Hive when running any command.

hive> show tables; FAILED: Error in metadata: javax.jdo.JDOFatalInternalException: Unexpected exception caught. NestedThrowables: java.lang.reflect.InvocationTargetException FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask 

This is in hive.log.

Obviously, there is a problem with the metadata database, but the error is pretty dumb, and the installation guide says nothing about setting up the metadata database.

Answer 1

I found the answer here:

"Shirish Reddy: remove $ HADOOP_HOME / build and everything should be fine. The answer is copied from Zheng

Oddly enough, after removing $ HADOOP_HOME / build, the problem disappeared.

Answer 2

I had the same problem.
Solutions - download this file: https://www.mysql.com/downloads/connector/j/ , unzip it, copy the jar from the inside to the location: /usr/lib/hive/lib (maybe in your case this is the place where the hive libs are located)
