I noticed the following log file in my installation:
My very minute complaint here is: Why is the user for MR history server mapred, when the log dir is named mapreduce. Or take it vice versa. Can we have this standardized somehow? Like both using mapreduce/mapreduce or, mapred/mapred?
I understand it would be difficult to make the change now, nor is the current form a problem in any way. I'm not suggesting we change this immediately and break things in any way, but would be good if we did fix this to be more consistent somehow in future.
