STATUS ERROR MESSAGE
I build a hadoop cluster with Ambari 2.7.3.0. Ambari notifies we need to restart some components, but I get the following error message when I restart them.
I guess there are some version issues as the message mentions.
Fail: The package hive-metastore is not supported by this version of the stack-select tool.
Is it due to the limited connection to the internet? Because of security issues, we use a local repository.
Unfortunately, I'm very new to Ambari and hadoop, so I cannot find any clue in this message.

I have a Spark application inside a test.py that I want to execute. Briefly speaking, I had Spark 2.3.0 installed, then would like to execute test.py. When I did it on my developing machine, Mac Book, everything is fine. BUT when attempting to do the same thing in a Docker container on my Mac Book, I would encounter the following exception which I've searched for possible hints from Google without triumph.
Clues Collected So Far
Running test.py without Docker on my laptop would be absolutely fine.
It seems to have something to do with record numbers when saving.
I. There are three actions where all have similar logic. In the Docker container, the first action is executed very well. But the next two would fail EVERY TIME when Spark tried to save results to AWS S3.
II. If I limit the dataframes as output in the last 2 actions like 5000, the program would be executed very well.
Logic of Spark Application
Retrieve data from MySQL or S3, do some computation, then store result onto AWS S3.

How I Run Docker
docker run -it --rm ${image id}
This is due to docker daemon killing the companion java process of the pyspark process because of memory limitations of the running container. The python counterpart detects the socket close and throws the EOF. The other exceptions are launched when trying to reconnect to the dead process.
You should check your process memory consumption (specially the java process which actually performs most of the spark operations) and adjust memory settings (--memory , --memory-swap) for your requirements when running the container (https://docs.docker.com/config/containers/resource_constraints/).

I have tried following things:
Uninstall and install certifi
and all the other steps mentioned in related answers on stack overflow.
Still unable to fix it.
Please help.
I was having the same problem, and after some searching, i came across this
https://bugs.python.org/issue28150
There is a command-line-runnable script ("/Applications/Python 3.6/Install Certificates.command") that uses pip to install certifi and creates a symlink in the OpenSSL directory to certifi's installed bundle location.
This worked for me, maybe you can take a look.
