Hi,
actually i solved the problem by trying below steps.
never try below steps, try only if you do not have option because you might loose some data from cluster
- stop all the elasticservices.
- used the elasticsearch-node command line which is already present search for this term elasticsearch-node you will come to know but on your own risk.
- using above tool and botstrap command from above tool i deatched the node from cluster and started the cluster and then rejoined the node in cluster.
- it was working fine then.
