[Elasticsearch] failed to obtain node locks

[Elasticsearch] failed to obtain node locks

elasticsearch 를 사용하다가 갑자기 종료가 되고 나중에 다시 시작하려고하니 아래와 같은 에러가 발생 하였다.

java.lang.IllegalStateException: failed to obtain node locks, tried [[/home/morriskim/elasticsearch/data/es-cluster]] with lock id [0]

stackoverflow에 찾아보니 jps로는 확인이 되지는 않지만 똑같은 머신에 elasticsearch 가 사용되는 경우가 있다고 하는데 아래와 같이 찾아서 프로세스를 종료하고 다시 시작 해보았다.

[morrrskim@spark01 bin]$ netstat -nlp | grep 9200
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp6       0      0 :::9200                 :::*                    LISTEN      3376/java
[morrrskim@spark01 bin]$ kill 3376
[morrrskim@spark01 bin]$ netstat -nlp | grep 9200
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

잘 시작된다.
