Ivan Mitic updated HADOOP-10090:
--------------------------------
Attachment: HADOOP-10090.branch-1.3.patch
Attaching a patch that goes with option #2 and addresses all the comments.
Luke, doing only the backport is not enough, the bug from this Jira will
remain.
Now we have to decide whether to do the backport in this Jira or not. Whether
we do it now or separately, I'd recommend that we change
MetricsSourceAdapter#getMetrics signature only to accept MetricsBuilderImpl
parameter. This is a package private method so this change should be ok.
Thoughts?
