Hello Experts,
I have implemented a custom log appender which inserts log messages to ElasticSearch.
Custom appender class works fine when it is run independently as executable jar.
But when I add this custom appender jar file to nifi "lib" directory, nifi stopped working - its not able to start.
I have below 2 dependencies in my appender jar -
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>7.15.0</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.15.0</version>
</dependency>
And Nifi has multiple processors related to ElasticSearch so the nar files of these processors also have same classes which are present in above 2 dependencies.
This looks to be the issue.
I need these ElasticSearch dependencies classes at bootstrap level for logger to get initialised.
But the nar files get loaded at later point, so I cant depend on the classes which are part of nar files.
What is the better approach to solve this issue ?
Any suggestion would be much appreciated.
Thanks
Mahendra
