[jira] [Reopened] (ACCUMULO-3212) Configuration objects created with CredentialProvider load defaults unnecessarily

["Billie Rinaldi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ACCUMULO-3212?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Billie Rinaldi reopened ACCUMULO-3212:
--------------------------------------

I think we actually need to load the defaults so it can find the default FS when reading a credential provider from HDFS (without having to specify the namenode in the credential provider URL).

> Jstack'ed a tserver and caught it in the middle of doing a bunch of URLClassloader and Jar stuff when creating a Hadoop Configuration. Obviously, this struck me as odd (given that I know those aren't "fast" methods).
> Looking at it some more, when I created the Configuration objects, I didn't pass in {{false}} so the defaults were getting loaded. Regardless of how expensive it actually is, it's unnecessary.
