Question

我尝试使用默认设置运行Elasticsearch，没有任何数据。我只需解压缩tarball并运行./bin/elasticsearch。问题是它只是永远挂起。日志中没有任何内容，stdout上没有输出。这是一台具有潜在安全限制和资源访问控制策略的计算机。

$ ./bin/elasticsearch -V
Version: 5.2.2, Build: f9d9b74/2017-02-24T17:26:45.835Z, JVM: 1.8.0_111

Linux版本：

$ uname -a
Linux [...] 2.6.18-406.el5 #1 SMP Fri May 1 10:37:57 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux
$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.11 (Tikanga)

爪哇：

它总是阻止同一个电话。我有一个非常类似的机器，Elasticsearch启动就好了。我无法弄清楚它是什么区别使它从一台机器开始并挂在另一台机器上。

对于记录，此问题是由NFS挂载点失败引起的。显然，如果其中一个挂起，Elasticsearch将通过NFS挂载点并挂起。

Elasticsearch在启动时挂起
