Elasticsearch服务器节点启动失败

Es服务器中一个节点启动时出现：

[hadoop@Slave1 service]$ ./elasticsearch start

Starting Elasticsearch...
Waiting for Elasticsearch..................
WARNING: Elasticsearch may have failed to start.

经分析原因是：文件权限的问题

[root@Slave1 ~]# cd ../usr/
[root@Slave1 usr]# chown -R hadoop:hadoop elasticsearch/
[root@Slave1 usr]# exit
logout
[hadoop@Slave1 usr]$ chmod 766 elasticsearch/
[hadoop@Slave1 usr]$ cd elasticsearch/elasticsearch-1.0.0/bin/service
[hadoop@Slave1 service]$ ./elasticsearch start
Starting Elasticsearch...
Waiting for Elasticsearch......
running: PID:5565

修改后正常启动
