Property [elasticsearch.version] is missing for plugin

[hackel]

I installed this plugin to my ES 2.4 instance and it worked fine. Now I've upgraded to 5.2, but ES refuses to start, with the above message. Does this plugin need to be removed prior to performing the upgrade? Maybe I missed it somewhere in the documentation, but if not this should probably be added. After removing the plugin, the upgrade seemed to go smoothly.

Does this plugin need to be removed prior to performing the upgrade?

Yes it needs to be removed. It works with 2.x only

[BismarckY]

don't bring elasticsearch-Head folder under the plugin folders of elasticsearch. bring it to anywhere else, and run: npm run start, it should work
