Have been trying to set it up for hours now. Nothing works.

  • Latest version does not seem to have winutils support, and using it causes errors when using some important methods. (EDIT: this is likely wrong, and the winutils stuff that I have should probably be fine.)
  • Older versions require to be built with Maven. However, that just gives me a PluginExecutionException.

I need to do this ASAP, preferably within the next 3 hours.

I have nowhere else to ask for help, it seems, especially considering that reddit-logo suspended an account I set up specifically for asking questions after I edited a relevant post.

Highly doubt that anybody will be able to help me.

EDIT2: the issue has, thankfully, been resolved. I was using Python 3.12, and switched to 3.11.8. That made the problem go away.

    • pip install pyspark and installing the latest version of Apache Spark leads to errors when calling pyspark.sql.DataFrame.show() methods of DataFrame objects.
    • pip install pyspark and installing an older version of Apache Spark, i.e. having a version mismatch between PySpark and Apache Spark, leads to errors even when instantiating a SparkSession.
    • pip install pyspark==3.3.4 previously led to an error - the system was unable to build wheels for the package. Now, it seems to install that way, but behaves the same as in the previous case.
    • Trying to build the 3.3.4 PySpark package manually with ./build/mvn using Bash from the appropriate directory led to Caused by: org.apache.maven.plugin.PluginExecutionException: Execution scala-compile-first of goal net.alchim31.maven:scala-maven-plu gin:4.4.0:compile failed.

    Running this code after having installed this stuff as in case 3:

    from pyspark.sql import SparkSession
    from datetime import datetime, date
    import pandas as pd
    from pyspark.sql import Row
    
    spark = SparkSession.builder.getOrCreate()
    
    df = spark.createDataFrame([
        Row(a=1, b=2., c='string1', d=date(2000, 1, 1), e=datetime(2000, 1, 1, 12, 0)),
        Row(a=2, b=3., c='string2', d=date(2000, 2, 1), e=datetime(2000, 1, 2, 12, 0)),
        Row(a=4, b=5., c='string3', d=date(2000, 3, 1), e=datetime(2000, 1, 3, 12, 0))
    ])
    df.printSchema()
    df.show()
    

    leads to this:

    Setting default log level to "WARN".
    To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

    System environmental variables JAVA_HOME, HADOOP_HOME, SPARK_HOME are configured. The relevant binary directories are included in the Path system environmental variable.
    PYTHON_SPARK is set to python.

    EDIT: Great, and now Maven can’t even attempt to build the package and throws the error

    Error occurred during initialization of VM
    Could not reserve enough space for 2097152KB object heap
    

    Just great.
