Nifi ExecuteStreamCommand Process error with IllegalStateException: Partition is Cloed

Hi Team ,

to pull the data from servers , we are running ssh commands using ExecuteStreamCommand processor . looks like some ssh commands/flowfiles are blocked in this processor due to no response from server(it is acceptable and common in server) . if it is the case ,this processor has to terminate the flowfile , but it is not and after sometime , ExecuteStreamCommand processor is hanging up .

Queue is showing some no of flow files ,but could not able to clear the queue in Nifi UI . looks ExecuteStreamCommand processor is trying or locked in it . what will be the solution to overcome this situation even if it is unable to process or run the ssh commads . Error we got in Nifi-app.log : 2017-03-27 04:03:56,125 ERROR [Timer-Driven Process Thread-82] o.a.n.p.standard.ExecuteStreamCommand ExecuteStreamCommand[id=5bda45d9-6601-14f0-3a44-294b3f5d994e] Transferring flow file StandardFlowFileRecord[uuid=633b08a2-f84d-4dc7-9a8c-175c5bc13b2e,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1490600595096-9, container=default, section=9], offset=0, length=0],offset=0,name=jmbfis01.northamerica.delphiauto.net,size=0] to output stream.

Re: Nifi ExecuteStreamCommand Process error with IllegalStateException: Partition is Cloed

How have you set up your shell script to handle closing on job timeout? I'm not aware of ExecuteStreamCommand having a hidden timeout property, though you could add something like a 'max wait' timeout if you wanted to do a PR.
