How can I check my solr index using Luke? I tried pointing to my index location (solr/core1/data/index). But I am getting the error
Unknown format version: -12
I got that error with a nightly build of lucene (4.x) and an older luke (1.0.1) - the latest currently available from its site.
Check out & build the latest luke from here:
http://code.google.com/p/luke/source/checkout
It reads latest lucene 4.x ok, 3.x versions as well.
As Mauricio suggests, this error means that your luke version is older than your solr version. Try updating to the newest version of Luke.

I mtrying to get back an older version of mongodb 2.4.6 with windows version .
I need some help to find it.
I'm a front-end developer and I need to do a Ckan Theme. To do so, I need a working source install of CKAN on my system. I'm using Mint 18.1 and installing Ckan 2.6.2.
Following the steps of the installation of ckan's docs I've got a warning and an error at step 6 as shown on the image.
As you can see the last line says SOLR schema version not supported: 2.7. Supported versions are [2.3] and I can't proceed with the installation. Searching on the Internet I found people having the same problem, but using Docker (have no idea what is this) and their solutions didn't work for me.
Because I have a really short time to build this theme I gave up CKAN 2.6.2 and installd 2.5.2 and everything worked fine.
The SOLR schema that comes with CKAN 2.6.2 is version 2.3, so somehow you have got 2.7, which is provided with later versions of CKAN. Maybe you installed CKAN master and the schema is lingering from then.
Here are some steps so that you can find out where the problem is:
You can check the version of the schema in the CKAN source repo on your disk:
grep 'name="ckan" version=' /usr/lib/ckan/default/src/ckan/ckan/config/solr/schema.xml
You would have then installed this file into Solr (in Step 5, using the 'ln' command). You can check the version in Solr:
grep 'name="ckan" version=' /etc/solr/conf/schema.xml
(When this file is changed, you need to restart SOLR (i.e. jetty) for it to take effect - see the docs again).
You can see what schema SOLR is actually using:
curl -s 'http://localhost:8983/solr/admin/file/?contentType=text/xml;charset=utf-8&file=schema.xml'|grep 'name="ckan" version='
Please do feed back on these.
It sounds like your Docker container for SOLR is a newer version than that is not compatible with CKAN 2.6.2.
I have Linux Ubuntu 12.04 installed and I'm trying to install nutch 1.5.1 and solr 3.6.1 and integrate theme together to crawl seed urls.
I'm using This tutorial to get this work.
I followed the steps before 3.2 and skipped to step 4 and I can access to
localhost:8983/solr/admin/
without error.
but when going to step 6 and copying schema.xml from conf folder of nutch to example/solr/conf folder of solr
solr/admin page occurs a java error,below:
How can I handle that?
one more thing to ask....
I have another tutorial for this that looks good but in first step it mentions that add some code to nutch-site.xml file in /conf/ and /runtime/local/conf/ folder
but in nutch folder there is no runtime folder.In step 4 this folder mentioned too.
any suggestion?
thanks in advance
This is just bit of red herring. The line that specifies version number something like:
<schema name="nutch" version="1.5.1">
is causing it because the value of version is being parsed as float. remove the extra dot. Change it to 1.5 or 1.51 to make it valid float and restart your solr instance. The exception should disappear.
Check,please, whether are Nutch 1.5.1 and Solr 3.6.1 compatible (are they having same versions of lucene-core and solr-solrj jars). I got some problems with incompatible versions, but not with 1.5/3.6 .
How to find the current version of Solr if the ip:8983/solr/admin is unreachable (the solr itself is running and responds)? Is it possible to read the current version from one of the files in the file system, or to build a custom php query to get this value? (if the query is needed please be kind to provide an example or reference, Thanks)
In my Solr 1.4.1 setup the war file was only solr.war, but I have found the version in CHANGES.txt
Lib name from solr-webapp/WEB-INF may be helpful for You: solr-core-4.4.0.jar
How are you deploying your solr war file. If you are using the default example folder then u can see one of the files to check the version. Or in ur application is the client need the version of solr? But what is the use of that?
In version 7.7.1 there is a file LUCENE_CHANGES.txt
Lucene Change Log
For more information on past and future Lucene versions, please see:
http://s.apache.org/luceneversions
======================= Lucene 7.7.1 =======================
(No Changes)
======================= Lucene 7.7.0 =======================
Changes in Runtime Behavior
The simplest solution is to go to the SOLR install location and execute:
./solr version
Example:
[root#node bin]# pwd
/usr/lib/ambari-infra-solr/bin
[root#node bin]# ./solr version
7.7.2
Uses command:
cd /opt/solr/bin/
./solr version
I have been searching for two days and have not been able to find an answer.
I have solr installed from the repos on an Ubuntu server running on tomcat 6. I have added the solr-cell jar and tika libraries.
I can run a curl command that works for some pdf files and indexes them fine, but it does not not work for others. At first i thought that some files were corrupted but that does not appear to be be the case. There does not appear to me to be any major difference between the ones thaqt work and those that don't.
The error i get is a 500 error - see example here
The curl request i make is:
$ curl 'http://mysolrserver.com:port/solr/update/extract?map.content=text&map.stream_name=id&extractOnly=true&commit=true' -F "file=#/absolute/path/to/file.pdf"
This does work for some PDFs fine, just not others.
I believe I have solr 1.4.0 installed.
Any help would be appreciated - thank you
--EDIT--
I am using Ubuntu 10.04.1 if that helps at all.
A NullPointerException is probably a bug. Report it to PDFBox and/or Tika.
OK the nightly snapshot of solr uses PDFBox 1.3.1 as opposed to the current stable which uses 0.7.* which is a fair amount of revision changes.
I can index all the pdfs using this snapshot version of solr. This seems to me something that will be
fixed in the next stable version.
