Alexandre Rafalovitch commented on SOLR-5931:
-
This case seems to be a mix of lacked-features, maybe-bug, and is again an old
version of Solr (so may have been fixed already).
I don't see any next action in this. I think it may be easiest to close this
issue and open a new one if something like this comes up against latest Solr.

When this issue will be fixed. I am in Production phase. After upgrading from
Solr 4.1 to 4.10.3, In final testing stage only I have found this issue . Could
you please suggest me any solution for this issue. And I have tried what Shalin
Shekhar Mangar suggested to add an xml file. Please suggest something.
Thanks in advance.

Addition: It also seems that properties linked via solr.xml core attribute
properties are not reloading anymore (version 4.6).
I used to use this file to dynamically enable/disable replication for specific
nodes and reload the core. Now I have to restart the whole Node.
This definitely worked before (version 4.3) Does this qualify as a bug
[~shalinmangar] ? ;)

Hi,
I also notice the same problem. (I am upgrading from 3.5 to 4.7)
I used to be able to define master.url in solrcore.properties, and any changes
there will take effect after an reload.
However, this is no longer working on 4.7.
I notice the doc says:
Starting with Solr4.0, the RELOAD command is implemented in a way that results
a live reloads of the SolrCore, reusing the existing various objects such as
the SolrIndexWriter. As a result, some configuration options can not be changed
and made active with a simple RELOAD...
IndexWriter related settings in indexConfig
dataDir location

Not sure if this includes properties defined in solrcore.properties file.

I can't say for sure whether this worked earlier (I only just started to use
solrcore.properties to control this, at the same time as I was upgrading
exactly like Gary, from 3.5 to 4.7).
In any case, I do consider it a bug, even if only in the sense of “violating
the principle of least astonishment.” : ) Applying configuration changes is the
whole point of reloading the core, for me at least — and changes in
solrconfig.xml and schema.xml and db-data-config.xml do get applied, so it
seems incongruous for solrcore.properties to be different.

I don't think it would have worked when I started looking at this code, but I
can't speak for what it did before...
I guess what needs to be done is to add a 'reload' method to CoresLocator which
will update the CoreDescriptor - at the moment CDs are immutable across the
lifetime of the CoreContainer, except for create() and unload() calls (which is
why this works if you unload and then create the core).

Yeah, this makes sense. The properties should be reloaded upon core reload. The
thing is that I can't find how these properties make their way into DIH. I'll
have to setup an example and step through with a debugger. I don't think I'll
find the time this week.

Gary Yue commented on SOLR-5931:
Is there a good workaround in the meantime?
We need a quick way to switch master URL on individual the slaves in case of
site issues. Updating solrconfig.xml directly for particular slave doesn't work
well because the change will get overwritten on each replication (unless we
change this in master's solrconfig as well)
Also, looks like i can't even call CREATE with the new property b/c starting
in solr 4.3+, it will return throw an error and ask you to call RELOAD
instead. (where as in solr3.x this i s essentially doing a RELOAD with new
properties)
thx!

When I change solrcore.properties for a core, and then reload the core, the
previous values of the properties in that file are still in effect. If I
*unload* the core and then add it back, in the “Core Admin” section of the
admin UI, then the changes in solrcore.properties do take effect.
My specific test case is a DataImportHandler where {{db-data-config.xml}}
uses a property to decide which DB host to talk to:
{code:xml}
dataSource driver=org.postgresql.Driver name=meta
url=jdbc:postgresql://${dbhost}/${solr.core.name} .../
{code}
When I change that {{dbhost}} property in {{solrcore.properties}} and reload
the core, the next dataimport operation still connects to the previous DB
host. Reloading the dataimport config does not help. I have to unload the
core (or fully restart the whole Solr) for the properties change to take
effect.

First, this would have been best asked on the user's list first...
But if you're using old-style master/slave configurations, you can configure
the replication to take particular files from the master and replicate them to
a differently-named file on the slave. See the example here (conffiles is the
param). Does that work?

Gary Yue commented on SOLR-5931:
thanks Eric. I'll ask on the user list for these kind of questions going
forward.
Regarding your suggestion: i am aware of such support, but not sure how this is
different from changing the replication for slave section of solrconfig.xml
on master solr. In both cases, you will need to make a change on master box,
and it can take up to few minutes for the files to be replicated (especially if
u have multiple level of replication hierarchy, for example master A- repeater
B-slave C). I understand that this may be the only workaround available
though, as there appears to be no other way of getting RELOAD to re-read a
local property file (like solrconfig.properties) which is not meant to be
replicable.

Is there a good workaround in the meantime?
We need a quick way to switch master URL on individual the slaves in case of
site issues. Updating solrconfig.xml directly for particular slave doesn't work
well because the change will get overwritten on each replication (unless we
change this in master's solrconfig as well)
{quote}
One option is using xinclude in your solrconfig.xml file. In solrconfig.xml,
you would have something like this:
{code}
requestHandler name=/replication class=solr.ReplicationHandler
xmlns:xi=http://www.w3.org/2001/XInclude;
lst name=slave
xi:include href=masterUrl.xml
xi:fallbackstr
name=masterUrlhttp://default_master:port/solr/corename/str/xi:fallback
/xi:include
!-- other replication options --
/lst
/requestHandler
{code}
With this config, normally masterUrl does not need to exist. When you need to
switch the master URL, create masterUrl.xml in the same location as
solrconfig.xml and reload/restart. It needs contents like this:
{code}
str name=masterUrlhttp://master_host:port/solr/corename/str
{code}
You can also do this without the fallback, in which case you'd use a config
like this and masterUrl.xml would always need to exist.
{code}
requestHandler name=/replication class=solr.ReplicationHandler
xmlns:xi=http://www.w3.org/2001/XInclude;
lst name=slave
xi:include href=masterUrl.xml /
!-- other replication options --
/lst
/requestHandler
{code}
As long as you don't include masterUrl.txt in the list of config files to
replicate, it won't get overwritten on the slave.
This is only to give you the general idea of xinclude. You can rearrange this
in any way that you require.
