Dale Richardson updated METRON-2312:
------------------------------------
Description:
When installing SOLR cloud, its been highly recommended to use the cluster
zookeeper ensemble rather then installing your in own mini-zk cluster just for
SOLR. For the past several years, its been standard practice to use a chrooted
/ namespaced environment for storing solr information in zookeeper. The
practical effects of this is to need to prepend '/solr' to any zookeeper
ensemble URLs. The use of chrooted zookeeper configurations is the default in
both lucidworks/HWX SOLR (from 4.0), and for Cloudera SOLR (not sure which
version but for many years). It has also been the documented recommendation
for Apache SOLR Cloud since approximately version 6.6.
End result is, if Metron is dealing with a SOLR cluster that has been installed
or updated any time in the past couple of years, it is dealing with a SOLR
configuration stored in a chrooted Zookeeper environment.
The problem is the Metron SOLR collection create/destroy scripts assume that we
are not using a CHROOTed environment, and fail badly when the expected SOLR
configuration is not present at the expected location in SOLR.

for a while before that.
