I am using Elasticsearch-2.3.1 and logstash-2.3.4 since quite long. Today I found a following warning in Elastic Search. I was trying to copy the logs but I think I press Ctrl+C and then an option appear to stop a job, I forgot the detail/name but I choose No/n. Then I also restarted the elasticsearch but thereafter I am getting following logstash errors.
Can you kindly guide me what is the issue?
NOTE: elasticsearch url http://localhost:9200/ is active and search is also working. Logstash and Elasticsearch both are running on same server. No changes are made on server including java version etc.
