Debugging HiveServer2 Docker container Remotely using Intellij

Collect Jstack,Jmap and other JVM diagnostics for a JVM running inside the docker container

RUN A hiveserver2 in docker containr (please follow the link http://rajkrrsingh.blogspot.com/2019/07/running-hiveserver2-on-docker.html)

Get the container id or container name for a running container.


docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0749ae15ece8 hive3-image "hive --service hive…" 20 hours ago Up 20 hours 0.0.0.0:10000->10000/tcp jovial_swartz


now you can use container id or the container name to connect with container interactively

docker exec -it 0749ae15ece8 /bin/bash
[hive@0749ae15ece8 ~]$ pwd
