[[cat-master]]
== cat master

`master` doesn't have any extra options. It simply displays the
master's node ID, bound IP address, and node name.

[source,sh]
--------------------------------------------------
% curl 'localhost:9200/_cat/master?v'
id                     ip            node

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

This information is also available via the `nodes` command, but this
is slightly shorter when all you want to do, for example, is verify
all nodes agree on the master:

[source,sh]
--------------------------------------------------
% pssh -i -h list.of.cluster.hosts curl -s localhost:9200/_cat/master
[1] 19:16:37 [SUCCESS] es3.vm
