Re: creating a new collection fails as SearchHandler can't be found
Hi
it was jars copied into a solr-zk-cli directory to allow easy running of
solr zk cmd line client. well i think that is what fixed tomcat! I've also
tried with jetty with a clean solr home and that also works and seems a
much cleaner way of running multiple instances (probably more to do with
rubbish tomcat sys admin skills on my part than anything else)
anyway cheers for help.

what exactly did hte logs errors look like *BEFORE* you started copying
libs arround?
as things stand right now, you've got at least 2 (possibly 3, i'm not
certain) copies of every Solr class in your classpath -- which can cause a
lot more classloader type errors (including ClassNotFound) then it will
ever solve, because of how the classloader hierarchy works -- if you have
to copies of ClassX loaded by two differnet classloaders, and ClassX
refers to SearchHandler but SearchHandler is not available in the same
ClassLoader that loaded ClassX, all sorts of not-fun ClassNotFound type
exceptions can happen.
Go back to a clean install, w/ a single solr.war file, and no manulaly
copied jars anywhere, and see if you still get problems with SearchHandler
when you create a collection.
if you do, then take another step back and try a single (tomcat) solr node
setup (no solrcloud) with an instanceDir already in place with a single
SolrCore
using hte example configs included in Solr 4.10.3 ... if that *STILL*
doesn't work, and you still get ClassNotFound errors then something is
jacked up with your tomcat setup/classpath (unless of coure you can still
reproduce the same problem with the same example configs using hte
Solr provided jetty -- in that case, the problem gets a lot more
interesting and your logs from *that* would be helpful to diagnose it)
: Any help would be appreciated.

creating a new collection fails as SearchHandler can't be found
Hi all
Creating a new collection fails with class not found:
org.apache.solr.handler.component.SearchHandler
Running under tomcat 7.0.59 with solr 4.10.3. Solr app looks to be deployed
ok and the web app looks fine when browsing.
An external zookeeper set up looks fine and the configs are loaded and
playing nicely.
However when I issue curl 'http://myserver:port
/solr/admin/collections?action=CREATEname=hotelPackagenumShards=4replicationFactor=1'
The collection fails to be created (shard_replica dir and data and index
across the servers get created but collection creation fails)
The full log is appended below. I thought it should be a straight forward
class not found problem but I just can't seem to fix this (few hours now).
I've even placed all the libs from solr.war into a directory and referenced
these from the solrconfig. You can see these being loaded in the below log.
Any help would be appreciated.
