I am configuring solr 5.5 and after starting the solr (bin/solr start), on accessing the admin panel, i see 500 error with description

HTTP ERROR 500

Problem accessing /solr/. Reason:

Server Error

Caused by:

org.apache.solr.common.SolrException: Error processing the request. CoreContainer is either not initialized or shutting down. at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:191) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:183) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1652) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:585) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:577) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:223) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1127) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:515) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1061) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:215) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:110) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:97) at org.eclipse.jetty.server.Server.handle(Server.java:499) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:310) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:257) at org.eclipse.jetty.io.AbstractConnection$2.run(AbstractConnection.java:540) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:635) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:555) at java.lang.Thread.run(Thread.java:745)

I took the zip from my friend's machine for which its working, and tried on my local, but same problem. Looks like some configuration problem with my machine.

Note : When i run the server on Clound mode (bin/solr start -e cloud -noprompt), i am able to access the admin panel.

There are several different possibilities for why you get this error.

I recommend checking whether clusterstate.json is empty or not, which you can find in the Zookeeper-ensemble. It should only contain "{}".

Further on would I check whether you have any shards in the SOLR_HOME-folder, and thereon delete them. SOLR_HOME is normally found at ./server/solr/.

Hope that works!

If you are giving your own folder for solr server. Make sure you have solr.xml copied there. This could be one of the reason.

Please try increasing the memory on the configuration file

/etc/default/solr.in.sh

SOLR_JAVA_MEM="-Xms2g -Xmx2g"
