URI is not absolute

[Massimiliano Ritossa]

Hi, i deployed a multi opencast servers 4.1 (1 admin, 1 presentation, 3 worker) on kubernetes. 

Opencast /data directory is shared with all 5 servers. The fact is that when i upload a stream, workflow process fails on "snapshot - Archive raw recording after ingest". This are few lines of the reported error from the admin server log :

ERROR | (AbstractAssetManager:302) - An error occurred

java.lang.IllegalArgumentException: URI is not absolute

What's URI are it referring to?

Thanks!

Hard to say since the error comes from an internal Java class which
does not give you much information. Anyway, my guess would be that it
is caused by one of these settings:

custom.properties:65:#org.opencastproject.episode.rootdir=${org.opencastproject.storage.dir}/archive

org.opencastproject.organization-mh_default_org.cfg:152:#prop.org.opencastproject.assetmanager.url=http://localhost:8080

Ok, i finally got it.

After a lot of tests and settings changes, i've finally understand what was the issue.

The setting

prop.org.opencastproject.assetmanager.url

would be better to remain unchanged. So i set it to http://localhost:8080 and everything worked.

Thank Lars, you drive me in the right direction.

Hi,
just to ensure it's no bug: To what did you set that value before?

Btb. letting it remain at its default value should be totally fine in
all cases unless you start to modify the default distributions.

Hi Lars, i tried to set prop.org.opencastproject.assetmanager.url to:

1) comment the setting ( #prop.org.opencastproject.assetmanager.url )

2) ${org.opencastproject.server.url}

3) ${prop.org.opencastproject.engage.ui.url}

4) <COMPLETE ADMIN SERVER URL WITH SCHEME AND PORT>

I forget to write that in the end, i also change the setting "server" in org.opencastproject.organization.mh_default_org.cfg from "localhost" to <PRESENTATION_SERVER_HOSTNAME>, but i think this detail is not important for my issue.

By the way, as written in the file, default value is ${org.opencastproject.server.url} but, in a multi-server context,

"server.url" is very ambiguous and seems to be not the right solution. So, forcing this:

prop.org.opencastproject.assetmanager.url=http://localhost:8080

Solved my issue.
