Does Ambari surpport yarn refreshQueues

    I’m trying Ambari1.4.4。
    1、It can configure YARN Queue without stop YARN。
    But when I use “yarn rmadmin -refreshQueues”, it not works.
    I have to restart YARN。
    2、I want to stop regionserver gracefully。
    But I can’t find in /usr/lib/hbase/bin。

    Is I miss something? any suggestion will be appreciated.

    Thank you

    1. Right now, ambari needs a service restart to pick-up capacity schedule queue changes. We are looking to add refresh queues in a future release.
    2. In Ambari 1.5.0 (currently GA) there is support for Region Server “decommission”, which does a drain.

    You can learn more about 1.5.0 (and see upgrade instructions) here:

    Thank you. And Is Ambari1.4.4 GA release too? I can’t find the answer in docs.

    Ambari 1.4.4 GA released in Feb. Ambari 1.5.0 went GA in early April (that’s where the Region Server decom feature support was added). Ambari 1.5.1 is currently under vote.

    Overall, watch this page for a summary of Ambari releases.
