WSO2 ESB - Cluster Environment Task Scheduling

I have a cluster environment which has a master and worker node (Hybrid configuration where master node also acts as a worker node). When I try to schedule a task on the master node, It gave an error 

WSO2 ESB - Could not initialize Start up controller. TaskManager not found. 
{org.apache.synapse.startup.quartz.StartUpController

which this post gave a solution

WSO2 ESB - Could not initialize Start up controller. TaskManager not found. {org.apache.synapse.startup.quartz.StartUpController

I added the required attribute and now I'am getting the following error.

ERROR {org.wso2.carbon.mediation.ntask.NTaskTaskManager} -  Scheduling task [[NTask::-1234::TestShedTsk]::synapse.simple.quartz] FAILED. Error: No available task nodes for resolving a task location {org.wso2.carbon.mediation.ntask.NTaskTaskManager}

    at org.apache.synapse.task.TaskScheduler.scheduleTask(TaskScheduler.java:140)
    at org.apache.synapse.startup.quartz.StartUpController.submitTask(StartUpController.java:150)

I have done the changes in the task-config.xml located in <ESB_HOME>\repository\conf\etc directory.

<taskServerMode>CLUSTERED</taskServerMode>

<taskServerCount>2</taskServerCount>

even though I'm still getting the above error.

For that error, you should have to start worker nodes with worker profile. As follows;

sh wso2server.sh -DworkerNode=true

When you are going to start Manager without workers, it may pop that error as worker nodes are not yet started. After you started worker nodes with worker profile, error should not be shown again.
