Rebuilt 2 nodes on my cluster last week with ES 1.6 (RPM), but the plugins failed to install. I stopped upgrading the whole cluster at this point until l can get the nodes all working with their plugins.
Has something changed to prevent plugins installing via:
/usr/share/elasticsearch/bin/plugin --install kopf --url http://$MYHTTPSERVER/pub/elasticsearch-kopf-master.zip
I get the results:
/etc/sysconfig/elasticsearch: line27: Set: command not found /etc/sysconfig/elasticsearch: line70: syntax error near unexpected token `in' /etc/sysconfig/elasticsearch: line70: ` in elasticsearch.yml (ES_HEAP_SIZE must also be set).' Unable to source environment file: /etc/sysconfig/elasticsearch
the same errors show for the 3 plugins that I install.
