- Use a separate HDFS sub-dir for every assignments-batch, in order to avoid any disrruptancies from multiple threads moving parquet-files from the same sub-dir. Multiple batches from the same worker may be processed at the same time. These sub-dirs are deleted afterwards.
...
- Treat the "contains no visible files" situation as an error. In which case the assignments-data is presumed to not have been inserted to the database tables.

Fix an issue, which could cause some background jobs to be executed more than 1 times. The previously executed jobs were not deleted from the global list fast enough, and they would be selected again, in case they were not finished before the scheduler started again.

- Use separate HDFS subdirectories for each worker in order to avoid seeing exceptions about "empty hdfs directory" when "loading" data to the database, because one worker has loaded data generated by multiple workers (since we use only 1 load operation for multiple parquet files).
...
- Store each worker's info in a hash-table, in order to efficiently know if we need to create new hdfs subdirectories. Also, this will help to issue "shutdown" requests to the workers in the future, as well as to know which worker has shutdown.

- In test-environment mode, check for already existing file-hashes only in the "payload_aggregated" table, instead of the whole "payload" view. This way the investigation for false-positive docUrls is easier, as we avoid checking against the millions of "legacy" payloads.
