[BUG] Default Docker container got broken

[ltregan]

Describe the bug I believe there was a new push of the image by datamechanics (5 days ago ?) and now sparkmagic docker image does not work anymore. If you log to the spark-1 container, and try ../bin/pyspark I get this error:

		Caused by: java.lang.IllegalArgumentException: Unrecognized Hadoop major version number: 3.1.0
    at org.apache.hadoop.hive.shims.ShimLoader.getMajorVersion(ShimLoader.java:174)
    at org.apache.hadoop.hive.shims.ShimLoader.loadShims(ShimLoader.java:139)
    at org.apache.hadoop.hive.shims.ShimLoader.getHadoopShims(ShimLoader.java:100)
    at org.apache.hadoop.hive.conf.HiveConf$ConfVars.<clinit>(HiveConf.java:368)

To Reproduce git clone https://github.com/jupyter-incubator/sparkmagic sparkmagic-dev cd sparkmagic-dev docker compose up

then create a new PySpark notebook and a simple command does not. work. eg. %data = [(1, 'John', 'Doe')]

The code failed because of a fatal error:
	Error sending http request and maximum retry encountered..

Some things to try:
a) Make sure Spark has enough available resources for Jupyter to create a Spark context.
b) Contact your Jupyter administrator to make sure the Spark magics library is configured correctly.
c) Restart the kernel.

Expected behavior PySpark kernel should work

Screenshots If applicable, add screenshots to help explain your problem.

Versions:

• SparkMagic 20.4 or master
• Livy (if you know it)
• Spark 2.4.7

Additional context I believe there was a new push of the image by datamechanics (5 days ago ?)

Hi @ltregan thanks for opening an issue. I'm looking into this today

[devstein]

@ltregan I'm unable to reproduce. Can you check if you are still running into issues?

[ltregan]

Still same issue, even after clearing the cache. Exact sequence is:

$ docker system prune -a -f
$ git clone https://github.com/jupyter-incubator/sparkmagic sparkmagic-dev
$ cd sparkmagic-dev
$ docker compose up

I am on Mac M1. Something fishy also is that CPU start at 20% (can be seen in the screenshots at the bottom) then goes up to 40% after a couple of minutes and stay there.

Full log then screenshots below.

@ltregan Thanks for the screenshots. I'm able to reproduce
