Steve Loughran commented on HADOOP-15001:
-----------------------------------------
Lessons of S3A here (HADOOP-13208 & predecessors?)
* easy for code to generate data faster than you can upload: needs ability to
block writer threads if the queue of pending uploads is too big. That's all
writers using the same FS.
* off heap storage is potentially better, though unconstrained growth still an
issue.
Look at {{S3ABlockOutputStream}} & helper classes
