getting SSLError: unknown group in the agent logs when enabling TLS encryption for Manager

New Contributor

OS:CentOS6.5 CDH5.1.0 

 

I followed this document to configuring TLS Encryption only for Cloudera Manager

http://www.cloudera.com/content/cloudera/en/documentation/cloudera-manager/v5-latest/Cloudera-Manage...

 

[root@SH01 ~]keytool -validity 1095 -keystore /etc/cloudera-scm-server/keystore/scm-keystore -alias jetty -genkeypair -keyalg RSA

 

"What is your first and last name?" I valued: SH01.com

 

[root@SH01 ~]# hostname

SH01

 

[root@SH01 ~]hostname -f

SH01.com

 

[root@SH01 ~]# vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

190.16.1.38 SH01.com SH01
190.16.1.39 SH02.com SH02
190.16.1.40 SH03.com SH03
190.16.1.41 SH04.com SH04
190.16.1.42 SH05.com SH05
190.16.1.43 SH06.com SH06
190.16.1.44 SH07.com SH07
190.16.1.45 SH08.com SH08

 

I can login CM mainpage but I can't start CM service after I finished all steps and restart all

 

It alert this :Service did not start successfully; not all of the required roles started: Service has only 0 Service Monitor roles running instead of minimum required 1.
