I cannot reproduce this error using the standard Hive Docker image, here is my operation list:

1. Launcher the Hive Docker container and SQLFlow Docker container

   > docker run -d -p 8888:8888 --name=hive sqlflow/gohive:dev python3 -m http.server 8899
   > docker run -it --rm -v $GOPATH:/go --net=container:hive --entrypoint bash -w 
   /go/src/github.com/sql-machine-learning/sqlflow sqlflow/sqlflow 

2. launch notebook and sqlflowserver process

   docker exec -it <sqlflow-container-id> bash 
   > bash /start.sh sqlflow-notebook &
   > sqlflowserver --datasrouce="hive://root:root@localhost:10000/iris"

3. Notebook logs:

Did I miss anything?

Solved. Unnecessary blank following the select clause cause this problem.
