Hello,
I'm trying to load some JSON data which has the following structure (this is a
sample):
{
"_index": "indexing",
"_type": "Event",
"_id": "AWAkTAefYn0uCUpkHmCy",
"_score": 1,
"_source": {
"dst": "127.0.0.1",
"devTimeEpoch": "1512437340000",
"dstPort": "0",
"srcPort": "80",
"src": "194.51.198.185"
}
}
In my file, everything is on the same line. My parser config is the following:
{
"parserClassName": "org.apache.metron.parsers.json.JSONMapParser",
"filterClassName": null,
"sensorTopic": "my_topic",
"outputTopic": null,
"errorTopic": null,
"writerClassName": null,
"errorWriterClassName": null,
"readMetadata": true,
"mergeMetadata": true,
"numWorkers": 2,
"numAckers": null,
"spoutParallelism": 1,
"spoutNumTasks": 1,
"parserParallelism": 2,
"parserNumTasks": 2,
"errorWriterParallelism": 1,
"errorWriterNumTasks": 1,
"spoutConfig": {},
"securityProtocol": null,
"stormConfig": {},
"parserConfig": {
},
"fieldTransformations": [
{
"transformation":"RENAME",
"config": {
"dst": "ip_dst_addr",
"src": "ip_src_addr",
"srcPort": "ip_src_port",
"dstPort": "ip_dst_port",
"devTimeEpoch": "timestamp"
}
}
],
"cacheConfig": {},
"rawMessageStrategy": "ENVELOPE",
"rawMessageStrategyConfig": {
"messageField": "_source"
}
}
But in Storm I get the following errors:
2019-04-25 16:45:22.225 o.a.s.d.executor Thread-5-parserBolt-executor[8 8]

How can I debug this?
Thanks
