Spark RDD’s doesn’t have a method to read csv file formats hence we will use textFile() method to read csv file like any other text file into RDD and split the record based on comma, pipe or any other. In the case where the file has already been created but there’s no logger you can add a live template to add the logger declaration. You can also read all text files into a separate RDD’s and union all these to create a single RDD. Use a slightly longer approach that properly closes. This has the side effect of leaving the file open, but can be useful in short-lived programs, like shell scripts. There are two primary ways to open and read a text file: Use a concise, one-line syntax. Step 3: Now select the + icon and select 1 JARs or Directories option as shown in.
Intellij search all files for text how to#
Step 2: After step 1 Select Modules at the left panel and select the Dependencies tab as shown in the below image. Java Reading from Text File Example The following small program reads every single character from the file MyFile.txt and prints all the characters to the output console: package import java.io.FileReader import java.io.IOException / This program demonstrates how to read characters from a text file. Adding a live template for a logger declaration You want to open a plain-text file in Scala and process the lines in that file. Step 1: Open your installed IntelliJ IDEA Project and go to the File > Project Structure as shown in the below image. I’ve added a suppress in as when you first create the file you haven’t used the logger and the warning annoys me. Head to IntelliJ preferences and search for template, you are looking for File and Code Templates section. While as you will see below Live Templates can handle the imports for you if you specify the whole package names I couldn’t get the file template to do the same. It would also be useful to have an easy way to add the logger declaration to a class missing it without all that typing or search then copy and pasting.
