- 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.
