4. Start master and a worker:
zzh@ZZHPC:~$ start-master.sh zzh@ZZHPC:~$ start-worker.sh spark://ZZHPC:7077
5. Install needed Python packages:
zzh@ZZHPC:~$ which pip
/home/zzh/venvs/zpy311/bin/pip
zzh@ZZHPC:~$ pip install --upgrade pip
zzh@ZZHPC:~$ pip install delta-spark==2.4.0
zzh@ZZHPC:~$ pip install deltalake==0.10.0
zzh@ZZHPC:~$ pip install pandas==2.0.1
zzh@ZZHPC:~$ pip install pyspark==3.4.1
zzh@ZZHPC:~$ pip install jupyterlab==4.0.2
zzh@ZZHPC:~$ pip install sparksql-magic==0.0.3
zzh@ZZHPC:~$ pip install kafka-python==2.0.2
Pandas version 2.0.1 doesn't work well. When executed 'import pands as pd', got error:
ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject
Uninstalled it and install the latest Pandas version:
zzh@ZZHPC:~$ pip uninstall pandas
Found existing installation: pandas 2.0.1
Uninstalling pandas-2.0.1:
Would remove:

/home/zzh/venvs/zpy311/lib/python3.11/site-packages/pandas/*
Proceed (Y/n)? Y
Successfully uninstalled pandas-2.0.1

9. Download Kafka 3.5.1 from https://kafka.apache.org/downloads :
export SPARK_HOME=$sfw/spark-3.4.1-bin-hadoop3 kafka_home=$sfw/kafka_2.13-3.5.1 PATH=$PATH:$SPARK_HOME/sbin:$SPARK_HOME/bin:$kafka_home/bin
10. Start Zookeeper (Kafka needs it to manage cluster metadata like broker registration and leader election. It is being replaced by KRaft.)
