Hi @Pierre Villard, Thanks for inputs, for example i have a GetFile processor and PutFile processor, Lets consider GetFile having 2lakh files, i started both at one time,for some reason after processing 100 files PutFile gone to error state it is not taking any inputs. So GetFile writing the continuously write data into queue. here how long will keep hold the data in a queue. is there any loss of data when it cross the 20000 flow files, let's consider my PutFile error is resolved after one week. still data in queue???? Thanks for giving response. ... View more

Hi Venkat, The problem is here you declared args parameter before the configuration you should declare the args after the configuration it won't give you an error. I tested it it's working fine. <workflow-app xmlns="uri:oozie:workflow:0.2" name="pdr-distcp-wf"> <start to="distcp-node"/> <action name="distcp-node"> <distcp xmlns="uri:oozie:distcp-action:0.2"> <job-tracker>${jobTracker}</job-tracker> <name-node>${nameNode1}</name-node> <configuration> <property> <name>oozie.launcher.mapreduce.job.hdfs-servers</name> <value>${nameNode1},${nameNode2}</value> </property> </configuration> <arg>${SourceDir}</arg> <arg>${TargetDir}</arg> </distcp> <ok to="end"/> <error to="kill"/> </action> <kill name="kill"> <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message> </kill> <end name="end"/> </workflow-app> ...
