Nifi : Alert mail to be sent when file not found in folder Is there a way using Nifi to poll a particular folder for a file . If file not found in that interval ,send a mail . Get File allows read a file ,but there is not failure relationship when using getFile processor. How can that be achieved ?

Hi Below are the steps i followed to feed nifi flow file to an output port. 1.Drop an "ExecuteProcess" Processor to canvas [or you can use TailFile Processor] to read lines added to "nifi-app.log". Auto Terminate relationship Failure. 2.Drop an OutputPort to the canvas and Name it 'spark', Once added, connect "ExecuteProcess" to the port for Success relationship. Im not able to enable the transmission of the output port .Have i missed anything? Please see the attached : .nifisparkreciever.png.39545-nifisparkreciever.png Using Nifi Open Source version 1.3.0

For Ex: USing getKafka -to read the stream PutHDFS to write to HDFS Can it be configured in the processor to create new folders when a new day starts and write the kafka topic data to that folder. Basically to maintain day wise folders in HDFS using putHDFS processor in nifi.

Thanks @Venkata Sudheer Kumar M .You rightly pointed the issue. Command was executing by default as root user. Resolution: I later updated the property under Nifi conf folder in the file bootstrap.conf as below run.as:hadoop The command execution was now as hadoop user and it ran successfully. Sqoop export is invokable via nifi execute processor.
