How do I access my Spark Driver account?

How to get W2 from Spark Driver?

I am using Spark 1.

4.2 version in Apache Spark and I wanted to run a custom program which returns number of lines present in a file. However, I have to give argument on the command line. When I am not giving arguments on the command line and when it works like Spark default program, it is showing as:
Scala> spark.read.text("/user/spark/data/lines.txt")

Res51: org.apache.rdd.txt

But when I am giving parameter on the command line by writing only file name like below: scala> spark.text("/user/spark/data/lines.txt")
Exception in thread "main" java.lang.IllegalArgumentException: Cannot read data from files:/user/spark/data/lines.txt because there is no file by that name.

From Spark docs: spark.text(path) Read data from path and return it as text. Note: Path must be a file system path.

What you are trying to achieve is to have the data loaded by the application itself not by a Spark task. To achieve this, use below option to your code: val textFile = sc.textFile("/user/spark/data/lines.txt")
Option 1: Use a Spark action to save a local file and read it with textFile function. Val fPath = File.createTempFile("temp-path", ".txt")
Val content = sc.textFile(fPath.getAbsolutePath).count
Val res = fPath.list() res.foreach(println) fPath.delete() Option 2: The following will create a directory at some location on HDFS and save the text file in that location. So in this case, you do not need to manually create an intermediate file.

Val dirPath = new File("/user/spark/data").getCanonicalPath val conf = sc.hadoopConfiguration conf.set("fs.

How to become a Spark Driver?

In this Spark tutorial, we'll learn from scratch.

What is Spark Driver? As the name suggests, the Spark driver is a user that uses Spark libraries. The driver provides an interface for accessing and manipulating the data stored in an Apache Hadoop cluster.

Why would one need a driver? It helps when a group of people are working together on the same problem. For example, if the team is building a car, they would need a driver to access the data that a car requires. The driver will be accessing the data that is available for cars, such as the tyre's dimension, material composition etc.

Similarly, if you are working on a machine learning project, you need a driver to access data from different sources such as the text data from Wikipedia, data of stock prices from NASDAQ, or weather data from Weatherspark. Now, we will discuss how to become a spark driver. How to become a Spark Driver? This tutorial assumes that you have already installed the latest version of Apache Spark (2.4). If you haven't, here is the link to download the latest version of Spark:

If you are not using Spark, you can also follow the steps given below: Download Spark 2.4: Extract the downloaded zip file to your preferred location. This will create a folder 'Spark-2.4' inside it.

In order to install Spark, first we need to download the Maven Repository. Clone the repo from here: where is the version of Spark that you have downloaded. We will use the latest version of Spark: '2.4)0'.

You can choose to clone a particular branch or the master branch. In our case, since we have downloaded the latest version of Spark, the default branch is named 'master'. To check the branch that has been cloned, run: mvn -q org.
