Answer 1

I applied this patch to ejabberd git, started it interactively using "make relive", and in the console I tried this:
elasticsearch:index(<<"my_index">>, <<"_doc">>, <<"id">>, #{<<"my_key">> => <<"my_value">>}).
{error,{failed_connect,[{to_address,{"localhost",9200}},
{inet,[inet],econnrefused}]}}
