design the interface of SEBAL worker code

[thiagomanel]

we need to defined the extension points for new version of the worker code (think about it as the fogbow plugins)

[thiagomanel]

This should also include the following contract of tag versioning

fmask_major_version.sebal_major_version.minor_version

[EsdrasVP]

Also, we need to put in contract that, when using Azure Workers, user must redirect its temporary files generated by execution to /mnt

This is necessary because Azure VMs do not have large disks, and bigger flavors use volumes mounted in working machine.

For our worker implementation, create a file named ".Renviron" in desired temporary folder and add the following line in R algorithm:

write("TMP = '<your-desired-tempdir>'", file=file.path(Sys.getenv('R_USER'), '.Renviron'))

[thiagomanel]

@EsdrasVP, maybe, we should have an $TMP to be specified in the contract and to be defined in each work implementation. Then, for the current worker $TMP equals /tmp and for azure, it equals /mnt (or something under /mnt).

This is the way to go. Perhaps we could look if $TMP is defined, and use it if so. Otherwise, the default would be to use /tmp. Notice that we probably can mount the Azure volume in the /tmp (instead of /mnt) and this would also solve the problem, but the proposed solution is more generic. — You are receiving this because you are subscribed to this thread.
