Invalid spark download link in Dockerfile

This is indeed very interesting project! thank you for making it public!

I just realised that the spark download link seems to be wrongly populated in Dockerfile. Please update it when you find time or highlight if i can make a PR. Thanks!

Incorrect.

# Download spark
RUN curl https://dlcdn.apache.org/spark/spark-3.3.1/spark-3.3.1-bin-hadoop3.tgz -o spark-3.3.1-bin-hadoop3.tgz \
 && tar xvzf spark-3.3.1-bin-hadoop3.tgz --directory /opt/spark --strip-components 1 \
 && rm -rf spark-3.3.1-bin-hadoop3.tgz

Correct.

# Download spark
RUN curl https://archive.apache.org/dist/spark/spark-3.3.1/spark-3.3.1-bin-hadoop3.tgz -o spark-3.3.1-bin-hadoop3.tgz \
 && tar xvzf spark-3.3.1-bin-hadoop3.tgz --directory /opt/spark --strip-components 1 \
 && rm -rf spark-3.3.1-bin-hadoop3.tgz

Also, Jupyter notebook doesnt show any token.

default memory settings too low for benchmark

I tried to run notebook with benchmark but was getting messages about java heap out of memory.

I found that one could set spark parameters from the notebook using:

%%init_spark
launcher.num_executors = 1
launcher.executor_cores = 8
launcher.driver_memory = '16g'
launcher.executor_memory = '16g'
launcher.conf.set("spark.driver.maxResultSize","4g")

I would suggest adding that and some comment to the notebook.

portotaxi.geojson Unexpected end-of-input: expected close marker for Object

In benchmark notebook on the cell with:

val fullFile = "/home/iceberg/data/portotaxi2.geojson"
val df = readGeojson(fullFile).repartition(50)
df.cache
df.createOrReplaceTempView("portotaxi")

I am getting the following error:

java.lang.RuntimeException: com.fasterxml.jackson.core.io.JsonEOFException: Unexpected end-of-input: expected close marker for Object (start marker at [Source: (String)"{"; line: 1, column: 1])

I'll try downloading the file outside of docker and try to open it in qgis but tail on the file look more or less normal. Not sure if there is another way to validate if the file was correctly downloaded?

I got the file by running:
wget https://star.cs.ucr.edu/datasets/portotaxi/download.geojson.gz -O - | gzip -d > /home/iceberg/data/portotaxi.geojson
in jupyter terminal.
Btw maybe it would be possible to use some jupyter cell magic commands to run it from notebook?
