In R and Sparklyr, writing a table to .CSV (spark_write_csv) yields many files, not one single file. Why? And can I change that?

Asked 2021-Nov-25 at 18:44

Background

I'm doing some data manipulation (joins, etc.) on a very large dataset in R, so I decided to use a local installation of Apache Spark and sparklyr to be able to use my dplyr code to manipulate it all. (I'm running Windows 10 Pro; R is 64-bit.) I've done the work needed, and now want to output the sparklyr table to a .csv file.

The Problem

Here's the code I'm using to output a .csv file to a folder on my hard drive:

Data will be divided into multiple partitions. When you save the dataframe to CSV, you will get file from each partition. Before calling spark_write_csv method you need to bring all the data to single partition to get single file.

You can use a method called as coalese to achieve this.

I suspect that's because of the white space. The quote must immediately follow the separator (comma). You can get around this by specifying ignoreLeadingWhiteSpace and ignoreTrailingWhiteSpace.

If you need to work with {{mustashes}} in the text without 'help' from Jinja interpolation, you can use !!unsafe type.

QUESTION

Inconsistent behaviour when attempting to write Dataframe to CSV in Apache Spark

Asked 2020-May-11 at 01:50

I'm trying to output the optimal hyperparameters for a decision tree classifier I trained using Spark's MLlib to a csv file using Dataframes and spark-csv. Here's a snippet of my code:

ANSWER

Answered 2020-May-11 at 01:50

I think I figured it out. I expected dfTosave.write.format("csv")save(path) to write everything to the master node, but since the tasks are distributed to all workers, each worker saves its part of the hyperparameters to a local CSV in its filesystem. Because in my case the master node is also a worker, I can see its part of the hyperparameters. The "inconsistent behaviour" (i.e. seeing different parts in each execution) is caused by whatever algorithm Spark uses for distributing partitions among workers.

My solution will be to collect the CSVs from all workers using something like scp or rsync to build the full results.

By default, Spark would be reading from HDFS.

If the file is at the HDFS root, just use this
