Oozie SSH action not returning

[Annie Lane]

Hi, I have an SSH action in my Oozie workflow like this:

 <action name="execute-docker-image">
        <ssh xmlns="uri:oozie:ssh-action:0.1">
            <host>${dockerHost}</host>
            <command>sudo</command>
            <args>docker</args>
            <args>run</args>
            <args>${dockerImageName}</args>
        </ssh>
        <ok to="ok-email"/>
        <error to="fail-email"/>
    </action>

But when I execute the Oozie job it doesn't complete for approximately 10
minutes, which I'm assuming is a timeout.

So, when I looked at the oozie logs on the ${dockerHost} machine (in the
oozie-oozi folder), I saw this in the stderr file:

"Not able to perform callback operation."

Is there some configuration I need to add to Oozie so that this SSH job can
call the callback?
