Tim Chermak commented on NIFI-6721: ----------------------------------- Hi, yes, this is from one of our other developers/users, but they said it is still an issue. Thanks -Tim > jms_expiration attribute problem > -------------------------------- > > Key: NIFI-6721 > URL: https://issues.apache.org/jira/browse/NIFI-6721 > Project: Apache NiFi > Issue Type: Bug > Components: Extensions > Affects Versions: 1.8.0 > Environment: Linux CENTOS 7 > Reporter: Tim Chermak > Priority: Minor > > The documentation for PublishJMS indicates the JMSExpiration is set with the > attribute jms_expiration. However, this value is really the time-to-live > (ttl) in milliseconds. The JMSExpiration is calculated by the provider > library as "expiration = timestamp + ttl" > So, this NiFi flowfile attribute should really be named jms_ttl. The current > setup works correctly when NiFi creates and publishes a message, but has > problems when you try to republish a JMS message. > GetFile -> UpdateAttibute -> PublishJMS creates a valid JMSExpiration in the > message, however, when a JMS has the expiration set, ConsumeJMS -> PublishJMS > shows an error in the nifi.--app.log file: > "o.apache.nifi.jms.processors.PublishJMS PublishJMS[id=016b1005-xxxxxx...] > Incompatible value for attribute jms_expiration [1566428032803] is not a > number. Ignoring this attribute." > Looks like ConsumeJMS set the flowfile attribute to the expiration value > rather than the time-ti-live value. Time-to-live should be jms_ttl = > expiration - current_time. > -- This message was sent by Atlassian Jira (v8.3.4#803005)
