The code below is based on An Introduction to boto's S3 interface - Storing Large Data.. To make the code to work, we need to download and install boto and FileChunkIO.. To upload a big file, we split the file into smaller components, and then upload each component in turn.

You can use method of creating object instance to upload the file from your local machine to AWS S3 bucket in Python using boto3 library. Here is the code I used for doing this: Figure 19: The Spark Submit command used to run a test of the connection to S3. The particular S3 object being read is identified with the “s3a://”prefix above. The Spark code that is executed as part of the ReadTest shown in Figure 20 is a simple read of a text file of 100MB in size into memory and counts the number of lines in it. The example above represents an RDD with 3 partitions. This is the output of Spark's RDD.saveAsTextFile(), for example. Each part-XXXXX file holds the data for each of the 3 partitions and is written to S3 in parallel by each of the 3 Workers managing this RDD. 1) ZIP compressed data. ZIP compression format is not splittable and there is no default input format defined in Hadoop. To read ZIP files, Hadoop needs to be informed that it this file type is not splittable and needs an appropriate record reader, see Hadoop: Processing ZIP files in Map/Reduce.. In order to work with ZIP files in Zeppelin, follow the installation instructions in the Appendix P laying with unstructured data can be sometimes cumbersome and might include mammoth tasks to have control over the data if you have strict rules on the quality and structure of the data..
