Hi Abhinav.

I am able to connect to presto for Hive and MongoDB via web console. When I am just trying to run the command:

show tables from default;

I am getting the following error message:

Error running command: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:4140

Can you help?

Thank you,
Arman

Hi,
I retry again today to just run the query in Presto and still getting this error:

presto:default> show tables from default;
Error running command: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:4140

What am I missing here? Is this a jave lib issue?
