I’m trying to bring up 6.2.1 after experience with 1.2 through 5.5, and it is a mess.
I’ve done solid good practice (Zookeeper ensemble, chroot, data on EBS volume),
but I’m stuck with a completely non-instructive stack trace.

We run a separate data directory and SOLR_HOME, which is poorly supported by 
the startup script. I gave up and used a symlink to make it sorta happy.

Still, I’m stuck with this.

org.apache.solr.common.SolrException: Error processing the request. CoreContainer is either
not initialized or shutting down.
       	at org.apache.solr.servlet.SolrDispatchFilter.doFilter(
       	at org.apache.solr.servlet.SolrDispatchFilter.doFilter(

I’ve tried loading configs with bin/solr and with I get useless error messages
from each of them.

I worked on a commercial search product for ten years, and this wouldn’t pass basic QA.
We need to do some work, people.
