https://community.cloudera.com/t5/Support-Questions/Scheduling-ExecuteStreamCommand-processor-with/m-p/230617#M192467 <P>I want to use ExecuteStreamCommand to submit a spark job via the shell, and I want to use GenerateFlowFile so that I can detect the spark job failure and RouteOnAttribute as suggested by Matt's answer <A href="https://community.hortonworks.com/questions/135072/how-to-handle-failure-of-nifi-executeprocess-proce.html">here</A>.<BR /><BR />I think it worked for detecting failure, but I can't make it scheduled correctly.<BR /><BR />If i want the whole flow (generation of the flow file, the ExecuteStreamCommand and Routng) to be executed every 1 minute, should I schedule the GenerateFlowFile every 1 minute and leave the ExecuteStreamCommand as default (0 schedule) or should I schedule both.<BR /><BR />I tried different combinations but it didn't work properly, I think the GenerateFlowFile keeps generating flow files but the ExecuteStreamCommand don't run multiple times. <BR /><BR /><BR /></P><P>another problem is that when I stop the ExecuteStreamCommand processor, it gets stuck, I can't change its configuration and I can't stop or start it again, It didn't work again until I restart NiFi.</P><P>Please help. </P> Wed, 30 Aug 2017 04:11:25 GMT MahmoudYusuf 2017-08-30T04:11:25Z
