Subject [jira] [Commented] (ACCUMULO-2992) Eliminate (use of) AccumuloConfiguration.getSiteConfiguration()
Date Mon, 14 Jul 2014 23:49:05 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14061444#comment-14061444
] 

Christopher Tubbs commented on ACCUMULO-2992:
---------------------------------------------

I took a look at the patch, and it looks fine, but what seems to be missing is an explanation
as to why the old method was deprecated.

This code was deprecated because clients shouldn't be expected to be able to have knowledge
of, or permission to use, a server's configuration. For backwards-compatibility and convenience,
the use of this deprecated code was left in the shell, with warnings suppressed, under the
understanding that eventually the shell would cease to use site configuration at all at some
point. Refactoring to use a different method doesn't address the original issue, but just
moves the concerns to a new location.

The use of site configuration should continue to be considered deprecated within client code
(including the shell), though, but that's not obvious with this patch, which in removing the
use of deprecated code, appears to have resolved any concerns. Perhaps along with this patch,
there's some comment which can be made to clarify in the code to future developers that the
use of SiteConfiguration now (vs. the old method) should be considered deprecated in the shell?

> The static method {{AccumuloConfiguration.getSiteConfiguration()}} has been deprecated
for a long time. [~ecn] got rid of a lot of uses in ACCUMULO-2401. This ticket is to get rid
of the rest. Each call can be replaced with:
> {code}
> SiteConfiguration.getInstance(DefaultConfiguration.getInstance());
> {code}
> The method itself can also be eliminated, as {{AccumuloConfiguration}} is not public
API, assuming the elimination would not cause a problem.
