             Summary: SolrInfoMBean-s category and hierarchy cleanup
                 Key: SOLR-9959
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: master (7.0)
            Reporter: Andrzej Bialecki 
            Assignee: Andrzej Bialecki 
            Priority: Blocker
             Fix For: master (7.0)

SOLR-9947 changed categories of some of {{SolrInfoMBean-s}}, and it also added 
an alternative view in JMX, similar to the one produced by {{SolrJmxReporter}}.

Some changes were left out from that issue because they would break the 
back-compatibility in 6.x, but they should be done before 7.0:
* remove the old JMX view of {{SolrInfoMBean}}-s and improve the new one so 
that it's more readable and useful.
* in many cases {{SolrInfoMBean.getName()}} just returns a FQCN, but it could 
be more informative - eg. for highlighter or query plugins this could be the 
symbolic name of a plugin that users know and use in configuration.
* top-level categories need more thought. On one hand it's best to minimize 
their number, on the other hand they need to meaningfully represent the 
functionality of components that use them. SOLR-9947 made some cosmetic 
changes, but more discussion is necessary (eg. QUERY vs. SEARCHHANDLER)
* we should consider removing some of the methods in {{SolrInfoMBean}} that 
usually don't return any useful information, eg. {{getDocs}}, {{getSource()}} 
and {{getVersion()}}.
