Issue has been resolved after un-installation of OpenJDK

Followed http://community.cloudera.com/t5/Cloudera-Manager-Installation/Problem-with-cloudera-agent/m-p/47799...

[#4]

Uninstalling OpenJDK solved it for me aswell. These packages were installed with Trifacta unfortunately in my case.

[#5]

Same for me! Trifacta should know better! 🙂 Is openJDK still a requirement for Trifacta?

Hi,

Could you please let me know how did you resolve this. I have the same issue. I have checked for jdk, but its the same in all the other servers as well. Not sure why there is issue with only 1 server

[root@ip-xx-x-xx-x cloudera-scm-agent]# rpm -qa "*jdk*"

java-1.8.0-openjdk-devel-1.8.0.144-0.b01.el7_4.x86_64

java-1.8.0-openjdk-headless-1.8.0.144-0.b01.el7_4.x86_64

jdk1.8.0_102-1.8.0_102-fcs.x86_64

copy-jdk-configs-2.2-3.el7.noarch

Thanks
