Sort of answering my own question here too...
It seems like I need to get the current core, and use that to
instantiate a new SolrCore with the same exact config, other than the
dataDir.
The documentation for SolrCore()'s constructor says:
"If a core with the same name already exists, it will be stopped and
replaced by this one"
But it's unclear to me whether this will do a graceful swap (like what
I want) or a hard shutdown of the old core.
Thanks,

Eache core can have the dataDir set explicitly.
<core name="core0" instanceDir="core0">
<property name="dataDir" value="/data/core0" />
</core>
<core name="core1" instanceDir="core1">
<property name="dataDir" value="/data/core1" />
</core>
If you want to do this with solrj, you would need to manipulate the
CoreDescriptor objects.
I'm hoping somebody can clarify what's up with the CoreDescriptor
class, since there's not much documentation.
As far as I can tell, when you create a new SolrCore, it saves off the
CoreDescriptor you pass in, and does nothing with it.
The constructor for SolrCore also takes a datadir param, so I don't
see how the CoreDescriptor's dataDir gets used during construction.
And changing the CoreDescriptor's dataDir has no effect, since it's
essentially a POJO.
So how would one go about changing the dataDir for a core, in a multi-
core setup?

Unless I'm missing something, I think you should be able to sort

a great
option.
So what's the best approach to making this work with SolrJ? The
low-level
solution seems to be
- create my own SolrCore instance, where I specify the data
directory
- use that to update the CoreContainer
- create a new EmbeddedSolrServer
But recreating the EmbeddedSolrServer with each index update feels
wrong,
and I'd like to avoid mucking around with low-level SolrCore
instantiation.
Any other approaches?
