Subject [jira] [Commented] (ACCUMULO-1985) Cannot bind monitor on remote host to all interfaces
Date Sun, 08 Dec 2013 18:48:35 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1985?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13842581#comment-13842581

Josh Elser commented on ACCUMULO-1985:
--------------------------------------

It looks like ACCUMULO-259 (specifically [b5c31dff|https://git-wip-us.apache.org/repos/asf?p=accumulo.git;a=commit;h=b5c31dff6d46eb419ea37db33d3f67dbb912a10c])
broke this way back in the day.

Previously, the static "create" method was used instead of the actual constructor to EmbeddedWebServer
([changes|https://git-wip-us.apache.org/repos/asf?p=accumulo.git;a=blobdiff;f=server/src/main/java/org/apache/accumulo/server/util/EmbeddedWebServer.java;h=b44788cbd01ab2a11ef2707b525d10fbee0329ba;hp=2d883ac423c02a3192f56ebbe51c7ff31335efb0;hb=b5c31dff6d46eb419ea37db33d3f67dbb912a10c;hpb=3131a518ec3d7acfaac3a58cdac349139a66a6b7]).
What it looks like is that in <1.5, the Monitor was always bound to all ports and >=1.5.0
actually "broke" this. Given that the changes were applied under a ticket that has nothing
to do with such a change, this makes me wonder if this was even desirable? [~vines], do you
remember at all?

I can see benefit in having the ability to not bind to all interfaces, but I wonder if we
should be changing *back* to bind to all by default and provide the means to bind to a specific
interface for that "new" case.

> To get the monitor to bind on all interfaces (typically, localhost and the public address),
you can specify 0.0.0.0 in conf/monitor.
> However, because 0.0.0.0 is also used in the ssh command to start the monitor on a remote
host, you can't get the monitor to start on all interfaces and on another host.
