Hi! Going through nested folders is pretty simple, there is a flag on the FileInputFormat that makes sure those are read.
Tricky is the part that all "00" files should be read before the "01" files. If you still want parallel reads, that means you need to sync at some point, wait for all parallel parts to finish with the "00" work before anyone may start with the "01" work. Is your training program a DataStream or a DataSet program?` Stephan On Wed, Feb 17, 2016 at 1:16 AM, Martin Neumann <mneum...@sics.se> wrote: > Hi, > > I have a streaming machine learning job that usually runs with input from > kafka.
