Spark SQL provides spark.read().csv("file_name") to read a file or directory of files in CSV format into Spark DataFrame, and dataframe.write().csv("path") to write to a CSV file. Function option() can be used to customize the behavior of reading or writing, such as controlling behavior of the header, delimiter character, character set, and so on. To write a Spark application, you need to add a dependency on Spark. If you use SBT or Maven, Spark is available through Maven Central at: groupId = org.apache.spark artifactId = spark-core_2.10 version = 0.9.1 In addition, if you wish to access an HDFS cluster, you need to add a dependency on hadoop-client for your version of HDFS: pyspark.sql.functions.date_format(date: ColumnOrName, format: str) → pyspark.sql.column.Column [source] ¶. Converts a date/timestamp/string to a value of string in the format specified by the date format given by the second argument. A pattern could be for instance dd.MM.yyyy and could return a string like ‘18.03.1993’.By default show () method displays only 20 rows from DataFrame. The below example limits the rows to 2 and full column contents. Our DataFrame has just 4 rows hence I can’t demonstrate with more than 4 rows. If you have a DataFrame with thousands of rows try changing the value from 2 to 100 to display more than 20 rows.The count of pattern letters determines the format. Text: The text style is determined based on the number of pattern letters used. Less than 4 pattern letters will use the short text form, typically an abbreviation, e.g. day-of-week Monday might output “Mon”.Apache Spark Fundamentals. by Justin Pihony.
