Hi,
here is the item of my json file.
//{"jurHash":"112256955","txnId":"vipus0E48BEC71E28C81F","ts":"2018-01-29 00:03:30.085 +0000","result.statusMessage":"Success","durationMillis":2,"requestId":"9999","extUserId":"testto demo","result.status":"0000","wsdlVersion":"1_8","operation":"createUser","_id":"car4be-w2-tc.1517184210085.15247464"}
The last attribute is "_id", I just met one problem that if I kept this format and imported it to logstash, the logstash would be stuck in "pipelines running" and not import the file successfully. But when I removed the last item or change "_id" into other name, the logstash will work fine.
