a mapper instance can be passed into Butler at init time, but that's not being done here:
    "/home/centos/stack/repos/dax_imgserv/python/lsst/dax/imgserv/locateImage.py",
        line 214, in _getImageButler
        butler = lsst.daf.persistence.Butler(self._dataRoot)

(mapper would be a 2nd arg).

it's possible there was a parent repo specified in the repo dir you copied over. you could look for a symlink inside the dir called _parent. If you find it, it would point to another repo on the originating filesystem. Look there for a file called _mapper. If you find that, copy it to the repo you have on your system, or copy the whole parent repo (and recreate the _parent symlink to be accurate if necessary). You may have to follow several _parent links. (Even if you find the _mapper right away, you may need to keep following _parent to make sure you have all the data needed to run the script)

ping me if you need help or clarification.

Subject: [QSERV-L] webserv and butler issue

I need some here, probably Nate, Serge or John will be able to help.

So I am trying to setup webserv for ipac... I copied this directory over:

/raid/lauren/rerun/LSST/STRIPE82L/v2/deepCoadd-results

from lsst-dev, and I ran Serge's ingest script, ending up
with some tables in the database becla_bremerton on our
lsst10 server.

I pointed webserv to lsst10 (like we did at Bremerton),
and tried to run some queries we used to run at Bremerton, eg


curl
'http://localhost:8661/image/v0/raw?ra=359.195&dec=-0.1055&filter=r' > 1.

(see full list at:

https://confluence.lsstcorp.org/display/DM/Webserv+for+SUI+Tests#WebservforSUITests-ExampleImageQueries
)


the imgserv is failing with

So why am I missing _mapper?

BTW, I suspect we need to redo the sample image queries (I'll need
help with that :).

Oh, and I just noticed that imgserv has this hardcoded:

database="DC_W13_Stripe82",
table="Science_Ccd_Exposure",

that is pretty ugly. We need to sort it all out, but right now I'd
like to just get to where we were during Bremerton meeting.
