This means that PySpark will attempt to check the data in order to work out what type of data each column is. I have a csv file located in the local folder. Is it possible to read this file data using pyspark? I have used below script but it threw filenotfound exception. df= spark.read.format(“csv”).option(“To load a CSV file you can use: Scala Java Python R val peopleDFCsv = spark.read.format("csv") .option("sep", ";") .option("inferSchema", "true") .option("header", "true") .load("examples/src/main/resources/people.csv") Find full example code at "examples/src/main/scala/org/apache/spark/examples/sql/SQLDataSourceExample.scala" in the Spark repo. df = spark.read.csv ("path/to/file.csv") df = spark.read.json ("path/to/file.json") df = spark.read.parquet ("path/to/file.parquet") Filtering is one of the most basic features for querying logs and is a crucial step to help reduce log size and isolate results into logs that matter.
