Question

我正在HDP（2.2.0.0-2041）上运行Ambari安装（1.7.0）。重新启动其中一台计算机后，内部IP地址已更改。这意味着Ambari无法找到它。（我们在AWS EC2上运行，因此主机名的格式为ip-x-x-x-x。）

如何通知Ambari新的IP地址？我到目前为止找到的唯一选择是添加一个新主机，但据我所知，这将清除机器。

这篇精彩的博客文章帮助了我们： http://www.swiss-scalability.com/2015/01/rename-host-in-ambari-170.html

基本上你需要登录Ambari的数据库。（不是GUI，实际的后端数据库）。最好完整地阅读博客文章，但我附上了实际让事情发生的重要秘诀。

如果您使用的是mysql：

SET FOREIGN_KEY_CHECKS=0; 
BEGIN;
UPDATE ambari.clusterhostmapping set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.configgrouphostmapping set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.host_role_command set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hostcomponentdesiredstate set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hostcomponentstate set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hostconfigmapping set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hoststate set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hosts set host_name = '${new-name}' WHERE host_name = '${old-name}';
COMMIT;
SET FOREIGN_KEY_CHECKS=1;

如果您使用的是postgresql：

ALTER TABLE ambari.clusterhostmapping DROP CONSTRAINT clusterhostmapping_cluster_id;
ALTER TABLE ambari.configgrouphostmapping DROP CONSTRAINT fk_cghm_hname;
ALTER TABLE ambari.host_role_command DROP CONSTRAINT fk_host_role_command_host_name;
ALTER TABLE ambari.hostcomponentdesiredstate DROP CONSTRAINT hstcmponentdesiredstatehstname;
ALTER TABLE ambari.hostcomponentstate DROP CONSTRAINT hostcomponentstate_host_name;
ALTER TABLE ambari.hostconfigmapping DROP CONSTRAINT fk_hostconfmapping_host_name;
ALTER TABLE ambari.hoststate DROP CONSTRAINT fk_hoststate_host_name;


BEGIN;
UPDATE ambari.clusterhostmapping set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.configgrouphostmapping set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.host_role_command set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hostcomponentdesiredstate set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hostcomponentstate set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hostconfigmapping set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hoststate set host_name = '${new-name}' WHERE host_name = '${old-name}';
UPDATE ambari.hosts set host_name = '${new-name}' WHERE host_name = '${old-name}';
COMMIT;


ALTER TABLE ambari.hoststate ADD CONSTRAINT fk_hoststate_host_name FOREIGN KEY (host_name) REFERENCES ambari.hosts(host_name);
ALTER TABLE ambari.hostconfigmapping ADD CONSTRAINT fk_hostconfmapping_host_name FOREIGN KEY (host_name) REFERENCES ambari.hosts(host_name);
ALTER TABLE ambari.hostcomponentstate ADD CONSTRAINT hostcomponentstate_host_name FOREIGN KEY (host_name) REFERENCES ambari.hosts(host_name);
ALTER TABLE ambari.hostcomponentdesiredstate ADD CONSTRAINT hstcmponentdesiredstatehstname FOREIGN KEY (host_name) REFERENCES ambari.hosts(host_name);
ALTER TABLE ambari.host_role_command ADD CONSTRAINT fk_host_role_command_host_name FOREIGN KEY (host_name) REFERENCES ambari.hosts(host_name);
ALTER TABLE ambari.configgrouphostmapping ADD CONSTRAINT fk_cghm_hname FOREIGN KEY (host_name) REFERENCES ambari.hosts(host_name);
ALTER TABLE ambari.clusterhostmapping ADD CONSTRAINT clusterhostmapping_cluster_id FOREIGN KEY (host_name) REFERENCES ambari.hosts(host_name);
