Subject [jira] [Comment Edited] (CASSANDRA-5881) Need "describe cluster;" functionality in nodetool or cqlsh

--------------------------------------------------------------------

Added the command to nodetool (./nodetool describecluster [thrift_api_port] )as cqlsh already
has a describe_cluster command. Mainly unhappy with how this works because if users aren't
on the default thrift port (9160) then they will have to supply the port they are using. Alternative
could be adding a flag to cqlsh's 'describe cluster' command and then execute a java call
to a function that works the same way this patch does. The function of the flag would be to
state that we want to get this info from all the nodes rather than retrieving it from the
local node's system tables.

> In order to be able to completely get rid of cassandra-cli we still need something like
"describe cluster;" callable from nodetool or cqlsh.  Describe cluster is different from just
querying the system tables in cqlsh in that it actually contacts each node.  Having a command
which does that is useful.
