Shred problems using Batch

I’ve struggled with this issue for 2 days now for our Dev instance of batch snow plow. I’ve tried all the tricks i’ve done in the past to fix enrichment or shred issues but nothing is working. i’ve been using snow plow for 4 years. there’s nothing in the EMR logs that tell me what the issue is. i’ve tried the following so far:

  • Cleaned out good/bad/archive folders for shredded folders in s3. this is sometimes a problem if there are too many files in each folder for snow plow. especially since we are not on s3a yet.
  • We are behind on updates but production is working fine so far. it’s just dev. EMR ETL runner version is below. prod and dev are in sync version wise
  • tried to increase number of cores to use in case there’s just a lot of data it has to shred but same thing.
  • i’ve gone through the troubleshooting doc for step issues, tried it all.
