---------------------------------
Hi Tobias,
This situation doesn't happen only when the storage is not shared. It seems it
has to do with how the Workspace decides what is 'local' and what is 'remote'
based on the working file repository root and the element uri (in WorkspaceImpl
'get' and 'getFile').
I noticed that in a distributed environment that has distinct admin and engage
servers, even using shared storage, when the compose-distribute-publish
workflow distributes a track for streaming, it always downloads the file.
In our case, we have in config.properties on the engage server:
org.opencastproject.admin.ui.url=http://admin1.mh-dev.harvard.edu
# The base URL of the file server. When using a shared filesystem between
servers, set all servers to use the same URL.
# If this is set to any value other than ${org.opencastproject.admin.ui.url},
the admin and file servers must use a
# single sign on (SSO) solution such as CAS to avoid requiring users to perform
multiple logins.
org.opencastproject.file.repo.url=${org.opencastproject.admin.ui.url}
Our engage server is engage1.mh-dev.harvard.edu. The distribution service runs
on the engage server and all distributed element urls are generated as
"http://engage1...";. So, when the streaming distribution operation runs and
tries to distribute something that has a url starting with "http://engage1...";,
different from "http://admin1...";, it assumes it is remote and downloads it.
The same will happen with an "rtmp://" url.
I am curious if there's a way things can be set up so this doesn't happen.
