Thanks for your reply Sebastian. We have a 3 node dev cluster setup on local servers. I tried nodetool commands on all 3 of them and response time was same (excess of 17 Seconds) and most in blocked state as you found out. I tried fiddling out with /etc/hosts file and on adding the line:
<private-ip> <hostname> This change Made the wait nearly minmal and has possibly resolved the problem. I can share the response on the same machine for which I had earlier shared (it was greater than 17 secs earlier) $ time nodetool version ReleaseVersion: 3.0.3 real 0m*1.197s* user 0m1.963s sys 0m0.284s This is a bit puzzling as I checked and ping is working in sub millisecond from host to self and other two servers, wondering where that time was being spent earlier.
