*** Reason for rollback *** We suspect that this is breaking RDE more, so we're going to rollout a cherrypick of this reversion. *** Original change description *** Upload to GCS before uploading to FTP Currently we encode and upload the deposite to GCS and the FTP server at the same time. This makes debugging harder as there are many possible points of failure, some of which are external and some internal. In this CL we start by encoding + uploading the deposit to GCS, and once that's done we copy the data from GCS to the FTP server. This will (hopefully) allow us to distinguish between errors on the FTP server and errors with the GCS connection. *** ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=201005260
