Github user james-sirota commented on the pull request: https://github.com/apache/incubator-metron/pull/127#issuecomment-222414251 On AWS the following did not work: /usr/metron/0.1BETA/bin/start_parser_topology.sh -s user -k xxx:9092 -z xxx:2181 I got a: 41 [main-EventThread] INFO o.a.c.f.s.ConnectionStateManager - State change: CONNECTED java.lang.NullPointerException at org.apache.metron.parsers.topology.ParserTopologyBuilder.build(ParserTopologyBuilder.java:57) at org.apache.metron.parsers.topology.ParserTopologyCLI.main(ParserTopologyCLI.java:232) Looking at the file here: https://github.com/cestella/incubator-metron/blob/METRON-174/metron-platform/metron-parsers/src/main/java/org/apache/metron/parsers/topology/ParserTopologyBuilder.java looks like it chokes on the sensor topic. However, listing the topics: /usr/hdp/current/kafka-broker/bin/kafka-topics.sh --list --zookeeper xxx:2181 bro enrichments pcap snort user yaf looks like i have it correct. My parser topology config looks as follows: { "parserClassName" : "org.apache.metron.parsers.csv.CSVParser" ,"writerClassName" : "org.apache.metron.writer.hbase.SimpleHbaseEnrichmentWriter" ,"sensorTopic":"user" ,"parserConfig": { "shew.table" : "enrichment" ,"shew.cf" : "t" ,"shew.keyColumns" : "user" ,"shew.enrichmentType" : "user" ,"columns" : { "user" : 0 ,"ip" : 1 } } } And is located under /usr/metron/0.1BETA/config/zookeeper/parsers/user.json Any suggestions?
