hello everyone,
We have an elasticsearch cluster which includes 3 nodes, elasticsearch 1.6(rpm package) was installed on them,and hold some indices on them.
I just updated the es version from 1.6 to 2.0 on the 3 nodes,following the official guide:
https://www.elastic.co/guide/en/elasticsearch/reference/current/restart-upgrade.html
then I started the elasticsearch serivce,but an error appeared and the services stopped on all the 3 node server:
and how can I solve it? thanks.
