> {quote}
> Looking at code again, I think we can improve the handling of EC files better:
> * In SetReplication#processPath, can we check if the file is EC before invoking setReplication()
on it?
> * -setrep also has a command switch -w to wait for the file to be replicated. Can we
ignore this if the file is erasure coded?
> {quote}
> Also, in fact, -setrep only make sense for HDFS file system...
