error with multicore CREATE action
Hey there,
I am using Solr 1.4 out of the box and am trying to create a core at runtime
using the CREATE action.
I am getting this error when executing:
http://localhost:8983/solr/admin/cores?action=CREATE&name=xxxxx&instanceDir=xxxxx&persist=true&config=solrconfig.xml&schema=schema.xml&dataDir=data

I don't know if I am missing something. Should I create manually de folders
and schema and solconfig files?

The point i'm trying to get at is that according to the initial comments
in this thread, CREATE does *appear* to be creating new instanceDirs on
the fly because of the mkdirs behavior as you mentioened -- my concern is
that the way you worded your reply suggests that this is a fluke, and
doesnt' work properly (ie: is everything properly initialized? does
persistence work?) ... if that's the case, then untill it does work, we
should propbably have an explict test for the instanceDir and fail if it
doesn't exist.
On the other hand: if it already works, it already works -- and we should
document it.

LotsOfCores still needs LotsOfWork :)

: directories by itself.
Shalin: I'm confused, wasn't this one of the original use cases for the
CREATE command as part of the "LotsOfCores" work you and Noble have been
pushing forward? I thought one of the goals was that a user could have a
single solrconfig.xml+schema.xml on disk somewhere, and then at run time
use the CREATE command to caused many, many new cores to be created (each
with a new/unqiue instanceDir).
If that isn't intended (and therefor: not handled well) then we should
probably make the CREATE command test for the existence of the specified
instanceDir and error if it doesn't already exist -- otherwise a typo in
an instanceDir file path could lead to some really unexpected behavior.

I guess when you try to add documents and an IndexWriter is opened, the data
directory is created if it does not exist. Since it calls File#mkdirs, all
parent directories are also created. I don't think Solr creates those
directories by itself.

Are there any use cases for CREATE where the instance directory
*doesn't* yet exist? I ask because I've noticed that Solr will create
an instance directory for me sometimes with the CREATE command. In
particular, if I run something like
http://solrhost/solr/admin/cores?action=CREATE&name=newcore&instanceDir=d:\dir_that_does_not_exist\&config=C:\dir_that_does_exist\solrconfig.xml&schema=C:\dir_that_does_exist\schema.xml
then Solr will create
d:\dir_that_does_not_exist
and
d:\dir_that_does_not_exist\data
for me (but not d:\dir_that_does_not_exist\conf).
Maybe this has to do with some particularly in my solrconfig.xml?
(There I've commented out the dataDir element because I prefer the
default behavior to what you get with "${solr.data.dir:./solr/data}".)

The instance directory and the configuration files should exist before you
can create a core. The core CREATE command just creates a Solr core instance
in memory after reading the configuration from disk.
