I have downloaded the watchman from the https://download.copr.fedorainfracloud.org/results/codeblock/watchman/epel-6-x86_64/watchman-2.9.5-1.fc20/watchman-2.9.5-1.el6.x86_64.rpm" and installed it on both servers.

Please help me in fixing the issue and let me know if I missed anything.

Thanks and Regards,
Ramesh AR

That version of watchman is really old. Try getting 4.9.0 from https://facebook.github.io/watchman/.
