Doug Cutting commented on HADOOP-3229:
--------------------------------------

The reporter passed to FileSystem#create() is to permit filesystems that might 
sometimes take a long time to open a file, like HDFS, to report progress during 
this time.  I don't know that it's worth passing it to the local filesystem in 
this case, but if we do, shouldn't we do it everywhere and not in just one 
place?

You dropped the reporting I added in CombineOutputCollector.  Why?


> Map OutputCollector does not report progress on writes
