Ambari代理无法再通过http://dom>:8440联系服务器?

ambari hortonworks-data-platform hadoop

slm yuvaeasy · 技术社区 · 6 年前

我们目前正在运行HortonWorks 2.6.5.0:

$ hadoop version
Hadoop 2.7.3.2.6.5.0-292
Subversion git@github.com:hortonworks/hadoop.git -r 3091053c59a62c82d82c9f778c48bde5ef0a89a1
Compiled by jenkins on 2018-05-11T07:53Z
Compiled with protoc 2.5.0
From source with checksum abed71da5bc89062f6f6711179f2058
This command was run using /usr/hdp/2.6.5.0-292/hadoop/hadoop-common-2.7.3.2.6.5.0-292.jar

操作系统是Centos 7:

$ cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)

我们最近开始注意到这些问题 ambari-agent 日志文件:

$ grep -i "error|warn" /var/log/ambari-agent/*
/var/log/ambari-agent/ambari-agent.log:WARNING 2018-07-30 14:03:50,982 NetUtil.py:124 - Server at https://hbase26-2.mydom.com:8440 is not reachable, sleeping for 10 seconds...

当这些开始发生时,我们无法再通过Ambari管理Hadoop集群的任何方面。所有的服务都显示出一些黄色的问号,并说“心跳停止”。

多次重新启动不允许我们恢复ambari,最终重新获得对集群的控制。
