CDH 5.7 installation stuck at Activation

New Contributor

I'm trying to install CDH in a two node cluster using

 

wget https://archive.cloudera.com/cm5/installer/latest/cloudera-manager-installer.bin

 

But it's stuck at activation for one of them.

When I checked /var/log/cloudera-scm-agent.log, I see this:

I chose all the defaults while installing using Cloudera Manager. How can I fix this? Thanks in advance.
