Chris Nauroth commented on HADOOP-9397:
---------------------------------------
The difference is the use of the helper run method for error reporting
(hadoop-dist) vs. not explicitly reporting errors (hadoop-yarn-project,
hadoop-mapreduce-project, etc.). As far as I can tell from revision history,
this difference has always been there, dating back to initial commit of the
code in HADOOP-7737 in 2011. I don't know that there is a legitimate reason
for it though. You could argue that hadoop-yarn-project,
hadoop-mapreduce-project, etc. should be doing something to check for errors
after each command and report it, more like what hadoop-dist does.
