[kepler-dev] adding new job manager

[Norbert Podhorszki]

Hi Ufuk,

This happens if your umask prohibits –x for the files. The scp creates the
file on the remote host with permissions according to umask.
You can try:
1. set your umask to –x friendly (on your ‘remote’ machine). Mine is 0022.
2. or use “local” instead of “karetta.be.itu.edu.tr” in the JobManager’s
target parameter (this will let the whole job class work with local java
operations instead of ssh)
3. or put your executable on the remote machine and enumerate it in the
‘remotefiles’ input for the JobCreate actor instead of the ‘executable’
input (the ssh operation will perform a cp command on the remote machine,
which preserves permissions)

Of course, it’s a bug. Thanks for pointing it out.

Norbert
