Daniel Pol commented on HDFS-8198:
----------------------------------
[~eddyxu] What's considered "client-side" for Teragen ? For example when I run
this from an external node "yarn jar hadoop-mapreduce-examples-3.0.0.jar
teragen". Is the external node the "client-side" or all the YARN nodemanagers
that execute the map tasks ? I'm asking because I don't see any cpu used on the
external node while I'm running hundreds of Teragen threads. Thanks for the
info on codec performance impact on the overall IO path.
