Github user DadanielZ commented on the issue: https://github.com/apache/incubator-eagle/pull/402 @yonzhang, I see now. In â AbstractHdfsAuditLogApplication.javaâ, there is an overrided function which use "HdfsAuditLogParserBolt" directly: ``` @Override public StormTopology execute(Config config, StormEnvironment environment){ ... HdfsAuditLogParserBolt parserBolt = new HdfsAuditLogParserBolt(); BoltDeclarer boltDeclarer = builder.setBolt("parserBolt", parserBolt, numOfParserTasks); ... } ``` that's why I wrote "AbstractMapRFSAuditLogApplication" and call "MapRFSAuditLogParserBolt". I think I should refactor the code in "AbstractHdfsAuditLogApplication" and let it call "getParserBolt" to get parserBolt, then extend this class for mapr application: ``` @Override public StormTopology execute(Config config, StormEnvironment environment){ ... BaseRichBolt parserBolt = getParserBolt(); BoltDeclarer boltDeclarer = builder.setBolt("parserBolt", parserBolt, numOfParserTasks); ... } ``` Will fix it.
