Subject [jira] [Commented] (HADOOP-9902) Shell script rewrite
Date Wed, 21 May 2014 20:36:42 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9902?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14005196#comment-14005196

Allen Wittenauer commented on HADOOP-9902:

That's very helpful! (Especially since that was going to be the next place I looked since
I just happen to have it cloned from git on my dev machine.... it's going to be one of the
first big tests I do as I work towards a commit-able patch. :D )

Bigtop looks like it is doing what I would expect: setting it for Hadoop, but not using it
directly.  Which seems to indicate that, at least as far as Bigtop is concerned, we could
expand the definition beyond "it must be a user".

Hadoop also uses HADOOP_IDENT_STR as the setting for the Java hadoop.id.str property.  But
I can't find a single place where this property is used. IIRC, it was used in ancient times
for logging and/or display, but if we don't need the property set anymore because we've gotten
wiser, I'd like to just yank that property completely.
