Amrit Sarkar updated SOLR-10865:
--------------------------------
Attachment: SOLR-10865.patch
Figured out what the problem is =>
To leverage the _processor=Template_ or _processor=Atomic_ or _processor = X_,
where X + "UpdateRequestProcessor", must and must have system property
*-Denable.runtime.lib=true*
Now when we start a SolrCloud with default settings, I don't think we have
*enable.runtime.lib* enabled in our configs. And the error we receive at the
end of the request is:
{code}
2017-06-12 11:05:55.517 WARN (qtp846947180-13) [c:gettingstarted s:shard1
r:core_node1 x:gettingstarted_shard1_replica_n1] o.a.s.c.PluginBag runtime
library loading is not enabled, start Solr with -Denable.runtime.lib=true
org.apache.solr.common.SolrException; org.apache.solr.common.SolrException: No
such processor Template
{code}
absolutely misleading. I guess improving the error message will make the user
make the necessary changes to make it work. A nested message is better to fix
this.
Patch attached with appropriate error or exception, which will help one figure
out what to fix, where to fix when we see "No processor".
> parameter processor=Template doesn't invoke TemplateUpdateProcessorFactory.
