@cotopaul Thanks for replying.   Apologize for not explaining myself properly. Here is the situation. The inititial data in the directory s3.bucket/data/to/be/processed/ looks like the following:      file0000.tar.gz      file0015.tar.gz      ...      file2345.tar.gz where 0000-0015-2345 are timestamp in 15 minutes increments. The end result should look like the following (same directory s3.bucket/data/to/be/processed/):      file0000/exctraded_files      file0015/extracted_files      ...      file2345/extracted_files where the folder is named after the original file, and it contains the extracted files.   What I am experiencing is that most of the folders are created as expected and the files are correctly extracted. However, I often get two or three files that seem not to get processed. I checked as you suggested if it might be a naming issue but that's not the case. I run another job pointing at those files who were extracted in the first place and the end result is what I expect.   Hope this was clear. Thanks for the help. ... View more
