> HTTP REST: top command returns wrong result via a client node if all server nodes left from topology: last server node is still in response.
> Steps to repeat
> 1. Create client node config: copy examples/config/example-ignite.xml to examples/config/example-ignite-client.xml and set client mode:
> {code:title=examples/config/example-ignite-client.xml|borderStyle=solid}
> ...
> <bean id="ignite.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
> <!-- Set to true to enable distributed class loading for examples, default is false. -->
> <property name="clientMode" value="true"/>
> <property name="peerClassLoadingEnabled" value="true"/>
> ...
> {code}
> 2. Copy libs/optional/ignite-rest-http directory into libs
> 3. Start two server nodes with example-ignite.xml:
> bin/ignite.sh examples/config/example-ignite.xml
> 4. Start client node with example-ignite-client.xml:
> bin/ignite.sh examples/config/example-ignite.xml
> 5. Now all nodes should print out following topology:
> {noformat}
> Topology snapshot [ver=3, servers=2, clients=1, CPUs=8, heap=3.0GB]
> {noformat}
> 5. Open url http://127.0.0.1:8082/ignite?cmd=top in your browser
> The response should be following
> {noformat}
