Subject [jira] [Commented] (HDFS-12007) Ozone: Enable HttpServer2 for SCM and KSM
Date Fri, 23 Jun 2017 05:32:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12007?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16060421#comment-16060421

Anu Engineer commented on HDFS-12007:
-------------------------------------

+1, this is the most amazing patch for Ozone. We can now see the JMX for both KSM and SCM.
I am so looking forward to the next set of patches. There is a missing package info, checkstyle
warning, which I will fix while committing.

There is also 2 consts  that is not used, which I will remove for now. if you need them for
the future patches please feel free to bring them back.

  // Common HTTP keys, used as postfix not as separated keys.
  public static final String BIND_HOST_KEY = "bind.host";
  public static final String ADDRESS_KEY = "address";


I am attaching the UI screen for rest the of the team. I also like the HDFS Green color more
than back UI. But I know this is not the final UI that you are working on.

> As a first step toward a webui for KSM/SCM we need to start and stop a HttpServer2 with
KSM and SCM processes. Similar to the Namenode and Datanode it could be done with a small
wrapper class, but praticly it could be done with a common super class to avoid duplicated
code between KSM/SCM.
> As a result of this issue, we will have a listening web server in both KSM/SCM with a
simple template page and with all the default servlets (conf/jmx/logLevel/stack).
> The https and kerberos code could be reused from the nameserver wrapper.
