I have a processor group that fetches data from ElasticSearch and stores it in mysql. Every time I run this processor group, NiFi will restart automatically after a while, which will cause my 'Scroll Duration=2m' to be disabled in ScrollElasticSearchHttp,and then I will never get the new data from the ES. I checked the log file and found no error message. this is the nifi-bootstrap_2018-10-09.log 2018-10-09 09:43:15,167 WARN [main] org.apache.nifi.bootstrap.RunNiFi Apache NiFi appears to have died.
