I was using previous version of elastic (1.7) , there we could install the head plugin from local directory using :
bin/plugin --install head --url file:///Full/Path/To/elasticsearch-head-master.zip
But when I tried the same in elastic 2.1 it was not working ... and then I tried to manually copied the content under plugin => head => _site . Then also es stopped working.
any suggestion how we can install the plugin from the local directory ..
