Elasticsearch, Failed to obtain node lock, is the following location writable

Question

Elasticsearch won\'t start using ./bin/elasticsearch. It raises the following exception:

- ElasticsearchIllegalStateException[Failed to obtain n         


        

Answer 1

I had an another ElasticSearch running on the same machine.

Command to check : netstat -nlp | grep 9200 (9200 - Elastic Port) Result : tcp 0 0 :::9210 :::* LISTEN 27462/java

Kill the process by, kill -9 27462 27462 - PID of ElasticSearch instance

Start the elastic search and it may run now.
