!wget -q https://downloads.apache.org/spark/spark-3.5.6/spark-3.5.6-bin-hadoop3.tgz
!tar xf spark-3.5.6-bin-hadoop3.tgz

### Install PySpark and findspark (helps locate Spark)
!pip install -q pyspark findspark duckdb  # duckdb for your script

### Set environment variables
import os
os.environ["JAVA_HOME"] = "/usr/lib/jvm/java-8-openjdk-amd64"
os.environ["SPARK_HOME"] = "/content/spark-3.5.6-bin-hadoop3"

### Initialize findspark
import findspark
findspark.init()

!wget https://downloads.apache.org/hadoop/common/hadoop-3.4.2/hadoop-3.4.2.tar.gz
!tar -xzvf hadoop-3.4.2.tar.gz && cp -r hadoop-3.4.2/ /usr/local/


JAVA_HOME = !readlink -f /usr/bin/java | sed "s:bin/java::"
java_home_text = JAVA_HOME[0]
java_home_text_command = f"$ {JAVA_HOME[0]} "
!echo export JAVA_HOME=$java_home_text >>/usr/local/hadoop-3.4.2/etc/hadoop/hadoop-env.sh

# Set environment variables
import os
os.environ['HADOOP_HOME']="/usr/local/hadoop-3.4.2"
os.environ['JAVA_HOME']=java_home_text

!alias hadoop="/usr/local/hadoop-3.4.2/bin/hadoop"
