Subject Re: Distributed queue problem with peerClassLoading enabled
Date Mon, 02 Nov 2015 10:35:33 GMT
Hi Mateusz,

Seems that either PRIVATE or ISOLATED deployment mode perfectly fits for
your task. Please try to switch to one of them.

CONTINUOUS mode reloads previously deployed classes only when 'userInfo'
changes. Refer to the documentation of this node.
In short to fix this you should increase the userVersion on the node that
changed Task class implementation

<beans xmlns="http://www.springframework.org/schema/beans"
    <description>Ignite Spring configuration file in gar-file.</description>

    <bean id="userVersion" class="java.lang.String">
        <constructor-arg value="2"/>

This is an expected exception. If you want to change serialVersionUID and
you use CONTINIOUS mode then you have to restart the whole cluster.
