thanks Rajesh. What we have observed is the decommissioned nodes show up as "UNREACHABLE" in "nodetool describecluster" command. Their status shows up as "LEFT" in "nodetool gossipinfo". This is observed in 2.1.12 version.
Decommissioned nodes did not show up in the "nodetool describecluster" and "nodetool gossipinfo" in 2.0.14 version that we use in another cluster. thanks Sai On Tue, Feb 16, 2016 at 2:08 PM, sai krishnam raju potturi < pskraj...@gmail.com> wrote: > hi; > we have a 12 node cluster across 2 datacenters.
