In the previous versions of Logstash one could run multiple conf files and it would run without any errors.
For instance ,
"abc-test.conf" and "abc-dev.conf" would run simultaneously .
However in logstash-5.4 running the first conf file somehow restricts the user from running the second one . The following error is returned :
[FATAL][logstash.runner ] Logstash could not be started because there is already another instance using the configured data directory. If you wish to run multiple instances, you must change the "path.data" setting.
I am guessing it is a change in the present usage of the logstash pipeline . Or is it something I am missing ? Kindly help.
