Action usage example

Below, you can see how to define an action that copies files to an S3 storage.

After configuring S3 credentials, you can copy files to an S3 storage by running an action like this:

copy2s3 -file /user/sergei/demoCopyS3/f1.txt -dest s3a://develop-test-bucket/f1.txt

You can run the following command to check that a file got copied:

$ hdfs dfs -cat s3a://develop-test-bucket/f1.txt

If there are no errors, you will see the file contents.
