HiveServer启动成功，但页面显示状态故障

适用版本

6.5.x。

问题现象

重启HiveServer成功，但是HiveServer一直处于故障状态。

原因分析

1. 查看HiveServer运行日志，发现HiveServer能够正常启动，但启动后，未出现异常，又收到停止的命令导致实例停止。

2. 查看nodeagent日志，发现健康检查为通过，导致nodeagent强制杀死HiveServer实例。

3. nodeagent通过JMX的方式检查实例（ip为本机ip：127.0.0.1），ps查看HiveServer的健康检查端口（21050）正常绑定在localhost的主机上。
4. 查看/etc/hosts的配置，localhost的ip映射不为127.0.0.1，导致无法连接。

解决方案

1. 备份/etc/hosts文件。
2. 修改/etc/hosts中localhost与127.0.0.1的正确映射，建议拷贝正常节点的配置到异常节点。
3. 如果是OMS节点需要重启OMS，其余节点需要重启Nodeagent。
