[jira] [Updated] (ACCUMULO-3012) Simplify DefaultConfiguration

["Bill Havanki (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ACCUMULO-3012?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bill Havanki updated ACCUMULO-3012:
-----------------------------------

    Resolution: Fixed
        Status: Resolved  (was: Patch Available)

After a delay, committed reviewed changes.

Reminder: there were two commits here, one for 1.5.x and one for 1.6.x. I did a merge -sours from 1.5.2-SNAPSHOT to 1.6.1-SNAPSHOT before committing the 1.6.x-specific change, so hopefully the history is tied up nicely.

Note: after committing, I noticed that I also fixed the usage statement for {{main()}} in {{DefaultConfiguration}} moved to {{ConfigurationDocGen}} - it still specified the option "generate-latex" instead of "generate-asciidoc". (See ACCUMULO-1327.)

> The current implementation of {{DefaultConfiguration}} has some downsides:
> * Its internal map of configuration defaults is built on-demand in its singleton instance, which drives the need to synchronize access to the singleton. The map could be built statically.
> * That same map could be made immutable as well.
> * Even though it uses a singleton, {{new DefaultConfiguration()}} is still permitted since the no-arg constructor isn't defined as private.
> * Calls to {{DefaultConfiguration.getInstance()}} cannot be easily mocked.
> * Its main method no longer has anything to do with it, and instead belongs in {{ConfigurationDocGen}}.
> Improve and simplify {{DefaultConfiguration}}.
