Hi Junping Du. Thank you for your work preparing this release.
I did the following things to test release Hadoop 2.6.4 rc0:- Downloaded
hadoop-2.6.4-RC0-src.tar.gz- built from source both package, install, and
eclipse:eclipse- Set up a 3-node, unsecured cluster with 3 queues, one of which
has preemption enabled- Ran a successful test to ensure that preemption would
happen to containers on the preemptable queue if they were needed for an
application on another queue.- Ran successful streaming and yarn shell tests
Junping, I did have a concern about labelled nodes and queues. Is full label
support backported to 2.6.4? I see that the syntax for the rmadmin command
lists label commands like -addToClusterNodeLabels and -replaceLabelsOnNode. I
was able to add a label (using -addToClusterNodeLabels) and I was able to
define a queue whose accessible node label was listed with my specified label.
However, when I tried to set the node label to a specific node using
-replaceLabelsOnNode, the label does not show up on the specified node in
cluster nodes UI (http://RM:8088/cluster/nodes). I also confirmed that
submitting a job to the labelled queue gets accepted but never runs, which is
the behavior I would expect if no node had the specified label. I will also add
that this procedure works fine in 2.7.
Thanks,-Eric Payne
