I tried to install "logstash-output-email" using below command and it could not installed due to firewall and then I came to know that there is a restriction that I can not use internet connectivity.
./logstash-plugin install logstash-output-email
Then I restarted the logstash and it started spawning new process ids every 5-10 secs and in the logs, it is looking for gem 'logstash-output-email'. Why is logstash not working when plugin installation has failed and installing the plugin has nothing to do with stating/stopping the logstash application.
I did verified what files has changed in the logstash install folder. One file has been created in the root install folder.
The error from the /var/log/logstash-stderr.log file:

Is it possible to edit the Gemfile to remove the last line manually and start the logstash. All I need is to start the logstash functioning so that I can do the debugging latter to install the logstash-output-email plugin.
