Hi Ethan,

So, the proper user for thredds would be the tomcat user, "tomcat" (in this case)?
Everything "thredds" and under is owned by "tomcat". Do I have to also make the group "tomcat" as well?
(that shouldn't matter, right?)

Are there any other salient files to look at. I will do another install shortly...
Java 1.7
Tomcat 7.0.39
Thredds 4.3.16

Will also set owner and group to tomcat just for completeness.
Will provide report of results...

If you can think of anything in the mean time please let me know.

P.S.
I'd rather have the property set in the file - it makes is explicit and leaves a trail of how things were run.

Thanks.

Hi Gavin,

We are not seeing any problems with this functionality in 4.3.

Rather than edit the tds.properties file directly, we recommend (see
[1]) using symbolic links or setting the property on the command-line
with a "-D" option. For instance:

-Dtds.content.root.path=/esg/content

However, editing tds.properties should work and I suspect that is not
the problem.

The nested stacktrace you include below, in particular this part

Caused by: java.lang.IllegalStateException: Content directory does not
exist and could not be created
  at thredds.server.config.TdsContext.afterPropertiesSet(TdsContext.java:304)

looks like a permission problem. Did the /esg/content/thredds directory
already exist when you started the TDS and got these errors?

This setup allows us to swap out thredds - more practically, *destroy*
the whole tomcat installation *without* *fubar'ing* peoples' hard built
catalogs (under *esgcet*).

Since this location also contains configuration portions that we have
added to allow for LAS interoperability, externalizing this from tomcat
is important to the sanity of the stack.  For the ESGF Node stack... all
"state" is kept under /esg such that everything else is solely mechanics
of transformations. 

/This has worked excellently in v4.2.10/ that we have been shipping with
out stack.  How can we get this same behavior for 4.3?

1) is this the exact property setting:

*tds.content.root.path=/esg/content*

what do the * mean?

2) any chance tomcat doesnt have write permission in that directory?

3) we are double checking how this is supposed to work

Hi, John,

So this is an excerpt from the tomcat's catalina.out

I believe that the issue may be because we move the content directory
out from under thredds and put it elsewhere.
We were able to do this successfully with 4.2.10 by modifying
the*tds.properties* file to have the entry
"*tds.content.root.path=/esg/content*".

So I guess the question is what has changed such that this is scenario
is no longer valid?
It smells like there may be some Spring things happening that assume
something about the location of things.

The idea is that we want to disassociate the location of the content
from the installation.
ESGF writes it's catalogs in a directory called esgcet this lives under
the thredds' content directory.
