I'm using config: ListS3: Bucket: test-empty-bucket01. Region: US West (Oregon). Write Object Tags: False. Write User Metadata: False. Communications Timeout: 30 secs. Endpoint Override URL: http://localhost:12345/ (My Ceph cluster) Use Versions: false. List Type: List Objects V1. Minimum Object Age: 0 sec. Requester Pays: False. FetchS3: Bucket: test-empty-bucket01. Object Key: ${filename}. AWS GovCloud (US). Communications Timeout: 30 secs. Endpoint Override URL: http://localhost:12345/ (My Ceph cluster). Requester Pays: False. My issues: When I use List Objects V2, ListS3 was not save current state file. When I use this config, it run very fast. But after 1-2 hours, ListS3 put issue: 2020-03-04 13:30:52,521 ERROR [Timer-Driven Process Thread-3] org.apache.nifi.processors.aws.s3.ListS3 ListS3[id=a3675f45-0170-1000-a9c4-825011327395] ListS3[id=a3675f45-0170-1000-a9c4-825011327395] failed to process session due to com.amazonaws.SdkClientException: Unable to execute HTTP request: Software caused connection abort: recv failed;
