Are you running go test in the docker container sqlflow/gohive:dev or on somewhere else?

jimdn commented 5 years ago

Fisrt i downloaded sqlflow.org/gohive and put it to my GOPATH, then I run go test -v in my own HADOOP environment: hadoop-2.7.7 hive-2.3.4 The first TestCase was passed which is testing the connection. But exec db.Query in the next TestCase, it panic.

We test gohive in a docker container. ref

TestOpenConnection initializes the configuration but does not connect to the hive server. I would suggest running the TestPing or db.Query to check the connection status.
