Connection to Hive via JDBC not working with multiple services

[#1]

Hello,

I have a service that connects to Hive via JDBC. When I start it on a machine (A) it's writing data to Hive. When I start the same service again on another machine (B) the call

pstmt.executeUpdate();

does not return. there is no exception or anything, I had it running for more than 10 minutes as well.

Why is it working on one machine, but not the other? it's the same connection string.

Thanks and BR

Can you check the logs on the HS2 server which you are pointing your JDBC client against?
