Summary: Use a thread-local cache in TokenIdentifier#getBytes to avoid creating many DataOutputBuffer objects Key: HADOOP-10587 URL: https://issues.apache.org/jira/browse/HADOOP-10587 Project: Hadoop Common Issue Type: Improvement Affects Versions: 2.4.0 Reporter: Colin Patrick McCabe Assignee: Colin Patrick McCabe Priority: Minor Attachments: HADOOP-10587.001.patch We can use a thread-local cache in TokenIdentifier#getBytes to avoid creating many DataOutputBuffer objects.
