Solr - Cores not initialised
Hi,
I’m running Solr 4.6.0 on an Ubuntu box. I recently made the following changes:
1. I edited Schema.xml to index my data by a column called timestamp.
2. I then ran the reload procedure as mentioned here https://wiki.apache.org/solr/CoreAdmin#RELOAD
After that, when I restarted Solr, I get a big red alert saying the following:
core0: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: No such core: core0
core1: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: No such core: core1
If I try to visit http://<IP Address>:8983/solr/core0/admin or http://<IP Address>:8983/solr/core1/admin, I get this
s XML file does not appear to have any style information associated with it. The document tree is shown below.

Re: Solr - Cores not initialised
Posted by Jack Krupansky <ja...@basetechnology.com>.
Usually a message like "SolrCore 'corexxx' is not available due to init
failure" means that you had a syntax error in your schema.xml or
solrconfig.xml so that it could not be successfully processed by Solr (which
is done in the "init" method.)
Do a diff between your schema and config files before and after your change
to see what your mistake might be. Feel free to post the two diffs here if
your mistake is not obvious.
The message "s XML file does not appear to have any style information
associated with it" suggests that you mangled some of the XML elements. It
appears that you mangled that message as well! Feel free to post the
complete message here as well.
