apache nifi executestreamcommand issue with using rsync

avatar

Hi,

 

we recently started evaluating apache nifi for our use cases.

 

Here is one of such sample pipe line that we have constructed

we have two processed one is Getfile which checks for files present in a local folder. Once they are available it sends them to the execute stream command. 

 

In 

execute stream command we want to send file that we received from getfile step to a remote linux server. The destination linux server doesn't have an FTP server hence cant use putFTP. This is the command I want to execute to transfer the file

sshpass -p '123' rsync -avz -e ssh --ignore-existing "${filename}" test@172.172.172.172:/home/test/nifioutput

 

Here is the configuration for execute stream command

put your command in a shell script named yourscript.sh and make sure NiFi has execute permissions.  rsync can be very slow so make sure you have a long timeout on the command.   i have seen rsync take 5 minutes to 20 hours.

can we not do it using the way I have done by configuring the properties in executestreamcommand.

Is there a way that I can see the log or else the complete scipt Nifi is trying to execute. This is the complete script that I want to execute

sshpass -p '123' rsync -avz -e ssh --ignore-existing /test.pdf test@172.16.4.59:/home/test/nifioutput

it's very hard to format a long call like that without wrapping it.   also you will need to fully list out directories so not /test.pdf but /the/actual/location/even/if/it/s/giant/test.pdf.  it may work.   you may also need to do /usr/bin/sshpass.   it is always easier to just write a simple runme.sh with the text in it, make it executable and test it.    also make sure nifi user has permissions to sshpass and if you are running on a cluster that all machines have that binary and have permissions
