Spark stream seems to be creating 0 bytes files even when there is no data. Also, I have 2 concerns here:
1) Extra unnecessary files is being created from the output 2) Hadoop doesn't work really well with too many files and I see that it is creating a directory with a timestamp every 1 second. Is there a better way of writing a file, may be use some kind of append mechanism where one doesn't have to change the batch interval.
