[syslog-ng] Connect syslog-ng to HDFS

[Czanik, Péter]

Hi,

As https://copr.fedorainfracloud.org/coprs/czanik/syslog-ng314/ also
writes: "Java is enabled, but JAR dependencies are not provided in package,
except for Elasticsearch http mode." The syslog-ng-java-deps.noarch
contains build time dependencies. Probably I should rename the package to
syslog-ng-java-build-deps...

Check the documentation at
https://www.syslog-ng.com/technical-documents/doc/syslog-ng-open-source-edition/3.16/administration-guide/33#TOPIC-956506
on how to download and configure HDFS related JAR dependencies.

Bye,
