i have a mounted directory (linux) on a windows machine and it's accessible via T:/
so if i create a file, say T:/example.txt, is it possible to change its ownership? i need it to be writable for other external process (i'm using postgres' gpfdist) to populate the file. i cant have that process to create the file and then populate it since i need to manually add headers to the file (limitaion on gpfdist side) and then output from the process will be appended.
in my case, the original user creating the file is talend. but i need to change it to gpfdist. or maybe talend remains but change the permission of the file so that it's writable?
the original user creating the file is talend
i wonder if talend can change the permission or owner of the file before the external process executes
another way is add gpfdist user to the same group as talend user so they have the same permission. this way the permission issue will go away.
