安装HDP集群过程中的报错
1、搭建ambari 时遇见的问题
[root@hadoop-master ~]# yum -y install ambari-server
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Resolving Dependencies
--> Running transaction check
---> Package ambari-server.x86_64 0:2.7.3.0-139 will be installed
--> Processing Dependency: postgresql-server >= 8.1 for package: ambari-server-2.7.3.0-139.x86_64
--> Finished Dependency Resolution
Error: Package: ambari-server-2.7.3.0-139.x86_64 (ambari-2.7.3.0)
Requires: postgresql-server >= 8.1
You could try using --skip-broken to work around the problem
** Found 4 pre-existing rpmdb problem(s), 'yum check' output follows:
bea-stax-api-1.2.0-9.el7.noarch has missing requires of jpackage-utils
bea-stax-api-1.2.0-9.el7.noarch has missing requires of jpackage-utils
stax2-api-3.1.1-10.el7.noarch has missing requires of jpackage-utils
tomcat-servlet-3.0-api-7.0.76-7.el7_5.noarch has missing requires of jpackage-utils
根据 下面四行所说 缺少 jpackage-utils 。转回本地源
yum -y install jpackage-utils
Error: Package: ambari-server-2.7.3.0-139.x86_64 (ambari-2.7.3.0)
Requires: postgresql-server >= 8.1
说明postgresql 版本过低 或者没有安装
先 yum-y update postgresql-server
根据反馈选择 安装还是升级
2、搭建hdp过程中修改了各节点主机名,导致在进行主机确认时,无法识别
解决办法:
重新安装ambari,将ambari相关的文件,程序都删除了(除了源码包),否则认证的时候无法成功
1、 通过ambari将集群中的所用组件都关闭
2、 关闭ambari-server,ambari-agent
3、清除浏览器的缓存
4,yum删除所有Ambari组件
5、删除除源码包外的所有ambari相关文件
6、清理数据库
3、在对主机进行检查认证时(常规报错)
EOF occurred in violation of protocol (_ssl.c:618)
ERROR 2020-07-09 10:35:24,213 NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions.
ambari openssl 版本问题:SSLError: Failed to connect. Please check openssl library versions.
1.检查os openssl版本,如果低于 openssl-1.0.1e-16.el6.x86_64 版本,请更新。
[root@node-1 ~]# rpm -qa | grep openssl
openssl-1.0.1e-57.el6.x86_64
openssl-devel-1.0.1e-57.el6.x86_64
更新openssl
[root@node-1 ~]# yum -y update openssl
重启ambari-server
ambari-server restart
2.若不行,
编辑 /etc/python/cert-verification.cfg 配置文件,将 [https] 节的 verify 项设为禁用:
vim /etc/python/cert-verification.cfg
verify=disable
修改/etc/ambari-agent/conf/ambari-agent.ini,在
vim /etc/ambari-agent/conf/ambari-agent.ini
[security]添加下面内容
ssl_verify_cert=0 force_https_protocol=PROTOCOL_TLSv1_2
重启ambari-agent
ambari-agent restart
3、安装服务时报错
javax.net.ssl.SSLHandshakeException: Client requested protocol TLSv1 not enabled or not supported
搭建的java jre配置问题
vim $JAVA_HOME/jre/lib/security/java.security
禁用、删除3DES_EDE_CBC即可,无需添加 TLSv1
修改完成后重启JAVA进程 (不行的话就重启服务器)
5、安装HDFS client报错
排查发现缺少依赖包:
解决办法:安装依赖包
http://mirror.centos.org/centos/7/os/x86_64/Packages/libtirpc-0.2.4-0.16.el7.x86_64.rpm
http://mirror.centos.org/centos/7/os/x86_64/Packages/libtirpc-devel-0.2.4-0.16.el7.x86_64.rpm
rpm -ivh libtirpc-0.2.4-0.16.el7.x86_64.rpm libtirpc-devel-0.2.4-0.16.el7.x86_64.rpm
