Subject Re: Re : decommissioned nodes shows up in "nodetool describecluster" as UNREACHABLE in 2.1.12 version

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
