JSAGA

Hi Lokendra,

Since the SSH adaptor currently does not cleanup anything, I guess this occurs only when you are using the FileTransfer attribute? If so, that bug is now fixed in the new snapshot (it was a bug in the JSAGA core engine).

Please note that the default behavior in this case will be to cleanup files, so you will have to explicitly set Cleanup attribute to 'false' to prevent them from being deleted.

Cheers,
Sylvain

Dear Sylvain,

Yeah, the error occurs when the FileTransfer attribute is used. But, I am using the latest snapshot and still getting the error.
I downloaded the libs from http://grid.in2p3.fr/software/jsaga-dev/download.html.

Hi,

I am unable to get this error with this snapshot when I set Cleanup=false.

Can you please provide more info, such as the list of SAGA attributes set, the file paths...

Cheers,
Sylvain

Hi Sylvain,

This is the snippet of my code.

URL serviceURL = URLFactory.createURL("ssh://localhost#SSH")

JobDescription desc = JobFactory.createJobDescription()
desc.setAttribute(JobDescription.EXECUTABLE, "groovy")
String[] arguments = ["test.groovy"]
desc.setVectorAttribute(JobDescription.ARGUMENTS, arguments)
desc.setAttribute(JobDescription.WORKINGDIRECTORY, "/tmp/jsagaTest")
desc.setAttribute(JobDescription.INTERACTIVE, "false") //turning the Batch mode
desc.setAttribute(JobDescription.OUTPUT, "output.txt");
desc.setAttribute(JobDescription.ERROR, "error.txt");
desc.setAttribute(JobDescription.CLEANUP,"false");
desc.setVectorAttribute(JobDescription.FILETRANSFER, (String [])['./test.groovy>sftp://localhost/tmp/jsagaTest/test.groovy#SSH','./output.txt<sftp://localhost/tmp/jsagaTest/output.txt#SSH']);

// create the job
Session session = SessionFactory.createSession(true)
JobService service = JobFactory.createJobService(session, serviceURL)
Job job = service.createJob(desc)
job.run()

Can you try this?

cat << EOF > job.txt
Executable=/bin/pwd
WorkingDirectory=/tmp/worker
Interactive=false
Output=output.txt
Error=error.txt
Cleanup=false
FileTransfer=/tmp/client/result.txt<output.txt
EOF

mkdir /tmp/client /tmp/worker
jsaga-job-run -f job.txt -r ssh://localhost

Hi Sylvain,

Your code tries to transfer the output.txt to a different directory on the remote machine. I tried that and it works, but still the output gets deleted from /tmp/worker/ even though Cleanup attribute is set to false.

Hi,

You can not have this behavior with the latest snapshot...

The only explanation I can think about is that you use some old libraries... Do you have environment variable JSAGA_HOME set to an older installation of JSAGA ?

Cheers,
Sylvain
