% curl 'localhost:9200/_cat/master?v' id ip node Ntgn2DcuTjGuXlhKDUD4vA 192.168.56.30 Solarr

all nodes agree on the master:
% pssh -i -h list.of.cluster.hosts curl -s localhost:9200/_cat/master [1] 19:16:37 [SUCCESS] es3.vm Ntgn2DcuTjGuXlhKDUD4vA 192.168.56.30 Solarr [2] 19:16:37 [SUCCESS] es2.vm Ntgn2DcuTjGuXlhKDUD4vA 192.168.56.30 Solarr [3] 19:16:37 [SUCCESS] es1.vm Ntgn2DcuTjGuXlhKDUD4vA 192.168.56.30 Solarr
