Robert Kanter updated YARN-3580:
--------------------------------
Attachment: YARN-3580.001.patch
When setting node labels, port 0 is considered a "wildcard" port, and the
{{CommonNodeLabelsManager}} applies the given label to all NMs that previously
had a label on that host. Due to the iteration ordering being different
between JDK 7 and JDK 8, this was changing the labeling from:
{noformat:title=JDK7}
z
host1:1
host3:1
y
host2:0
host3:0
x
host1:0
{noformat}
to
{noformat:title=JDK8}
x
host1:1
host1:0
y
host3:0
host2:0
z
host3:1
{noformat}
The patch fixes the problem by using different port numbers. It also cleans
the test up a little.
