Flow push does not work in cluster environment

This issue is detected in our csit job:

https://jenkins.opendaylight.org/releng/view/CSIT-3node/job/openflowplugin-csit-3node-clustering-only-stable-lithium/

To reproduce:

1) Install 3 node cluster setup with latest stable Lithium and feature odl-openflowplugin-flow-services-ui-li

2) Start normal mininet and point to 3 controllers:

ovs-vsctl set-controller s1 "tcp:192.168.0.101:6633" "tcp:192.168.0.102:6633" "tcp:192.168.0.103:6633"

sudo mn --controller 'remote,ip=192.168.0.101,port=6633' --topo tree,1 --switch ovsk,protocols=OpenFlow13

3) Push a sample flow to DS:

PUT http://192.168.0.101:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/0/flow/1
{
"flow-node-inventory:flow": [
{
"id": "1",
"priority": 2,
"flow-name": "flow1",
"table_id": 0,
"hard-timeout": 0,
"instructions": {
"instruction": [
{
"order": 0,
"apply-actions": {
"action": [
{
"order": 0,
"output-action":

{ "output-node-connector": "1" }

}
]
}
}
]
},
"idle-timeout": 0,
"match": {
"ipv4-destination": "10.0.10.0/24",
"ethernet-match": {
"ethernet-type":

{ "type": 2048 }

}
}
}
]
}

Flow replicates in DS config but nothing is sent to switch.

4) Send RPC Flow Add:

POST http://192.168.0.101:8181/restconf/operations/sal-flow:add-flow
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<input xmlns="urn:opendaylight:flow:service">
<node xmlns:inv="urn:opendaylight:inventory">/inv:nodes/inv:node[inv:id="openflow:1"]</node>
<table_id>0</table_id>
<priority>2</priority>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
</ethernet-match>
<ipv4-destination>10.0.1.0/24</ipv4-destination>
</match>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<output-action>
<output-node-connector>1</output-node-connector>
</output-action>
<order>0</order>
</action>
</apply-actions>
</instruction>
</instructions>
</input>

Again nothing is sent to switch.

In both cases there is no message in karaf log indicating error or anything.
