ASF GitHub Bot commented on NIFI-3204: -------------------------------------- Github user joewitt commented on the issue: https://github.com/apache/nifi/pull/1561 The more I look at this processor the more I think the mistake was in allowing it to have wildcards and to run without incoming flow files. Had it been restricted to simply deleting the content of a path specified by a given flowfile it would be much more clear. > delete hdfs processor throws an error stating transfer relationship not > specified even when all relationships are present > ------------------------------------------------------------------------------------------------------------------------- > > Key: NIFI-3204 > URL: https://issues.apache.org/jira/browse/NIFI-3204 > Project: Apache NiFi > Issue Type: Bug > Affects Versions: 1.0.0, 1.1.0 > Reporter: Arpit Gupta > > Following flow was setup > get file -> extract text -> delete hdfs > A bunch of files were written each having one line which was the path to > delete. Some of these path's were files, some were directories and some were > patterns. Extract text would extract the line and assign to an attribute > which delete hdfs would use to populate the path to delete. > However the processor would run into an error when ever it tried to process > the path which was a pattern matching multiple paths. > {code} > 2016-12-14 11:32:43,335 ERROR [Timer-Driven Process Thread-7] > o.a.nifi.processors.hadoop.DeleteHDFS > DeleteHDFS[id=fed0acf6-0158-1000-b7ab-8cc724e4142d] > DeleteHDFS[id=fed0acf6-0158-1000-b7ab-8cc724e4142d] failed to process session > due to org.apache.nifi.processor.exception > .FlowFileHandlingException: > StandardFlowFileRecord[uuid=af8be94a-e527-4203-bb87-a0115f84e582,claim=StandardContentClaim > [resourceClaim=StandardResourceClaim[id=1481656798897-1, container=default, > section=1], offset=6518, length=75],offset=0,name=noyg3p7km8.txt,size=75] tr > ansfer relationship not specified: > org.apache.nifi.processor.exception.FlowFileHandlingException: > StandardFlowFileRecord[uuid=af8be94a-e527-4203-bb87-a0115f84e582,claim=StandardContentClaim > [resourceClaim=StandardResourceClaim[id=1481656798897-1, container=default, > sectio > n=1], offset=6518, length=75],offset=0,name=noyg3p7km8.txt,size=75] transfer > relationship not specified > 2016-12-14 11:32:43,335 ERROR [Timer-Driven Process Thread-7] > o.a.nifi.processors.hadoop.DeleteHDFS > org.apache.nifi.processor.exception.FlowFileHandlingException: > StandardFlowFileRecord[uuid=af8be94a-e527-4203-bb87-a0115f84e582,claim=StandardContentClaim > [resourceClaim=StandardResourceClaim[id=1481656798897-1, container=default, > section=1], offset=6518, length=75],offse > t=0,name=noyg3p7km8.txt,size=75] transfer relationship not specified > at > org.apache.nifi.controller.repository.StandardProcessSession.checkpoint(StandardProcessSession.java:234) > ~[nifi-framework-core-1.1.0.jar:1.1.0] > at > org.apache.nifi.controller.repository.StandardProcessSession.commit(StandardProcessSession.java:304) > ~[nifi-framework-core-1.1.0.jar:1.1.0] > at > org.apache.nifi.processor.AbstractProcessor.onTrigger(AbstractProcessor.java:28) > ~[nifi-api-1.1.0.jar:1.1.0] > at > org.apache.nifi.controller.StandardProcessorNode.onTrigger(StandardProcessorNode.java:1099) > ~[nifi-framework-core-1.1.0.jar:1.1.0] > at > org.apache.nifi.controller.tasks.ContinuallyRunProcessorTask.call(ContinuallyRunProcessorTask.java:136) > [nifi-framework-core-1.1.0.jar:1.1.0] > at > org.apache.nifi.controller.tasks.ContinuallyRunProcessorTask.call(ContinuallyRunProcessorTask.java:47) > [nifi-framework-core-1.1.0.jar:1.1.0] > at > org.apache.nifi.controller.scheduling.TimerDrivenSchedulingAgent$1.run(TimerDrivenSchedulingAgent.java:132) > [nifi-framework-core-1.1.0.jar:1.1.0] > at > java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) > [na:1.8.0_92] > at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) > [na:1.8.0_92] > at > java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) > [na:1.8.0_92] > at > java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) > [na:1.8.0_92] > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > [na:1.8.0_92] > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > [na:1.8.0_92] > at java.lang.Thread.run(Thread.java:745) [na:1.8.0_92] > 2016-12-14 11:32:43,335 WARN [Timer-Driven Process Thread-7] > o.a.nifi.processors.hadoop.DeleteHDFS > DeleteHDFS[id=fed0acf6-0158-1000-b7ab-8cc724e4142d] Processor > Administratively Yielded for 1 sec due to processing failure > {code} -- This message was sent by Atlassian JIRA (v6.3.15#6346)
