-------------------------------------
Summary: lock contention around configuration settings impacts
tablet server performance
Key: ACCUMULO-4458
URL: https://issues.apache.org/jira/browse/ACCUMULO-4458
Project: Accumulo
Issue Type: Bug
Components: tserver
Affects Versions: 1.8.0, 1.7.1
Reporter: Sean Busbey
Assignee: Sean Busbey
Priority: Critical
Fix For: 1.7.3, 1.8.1, 2.0.0
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.
