      Description

      While investigating a pretty severe performance regression comparing YCSB against 1.6 and 1.7, I found a fair bit of lock contention around getting configuration values. This was improved by ACCUMULO-4388, but various threads eventually all started contending on the configuration values expected from the site xml files.
