Chris Nauroth created HDFS-4633: ----------------------------------- Summary: TestDFSClientExcludedNodes fails sporadically if excluded nodes cache expires too quickly Key: HDFS-4633 URL: https://issues.apache.org/jira/browse/HDFS-4633 Project: Hadoop HDFS Issue Type: Bug Components: hdfs-client Affects Versions: 3.0.0 Reporter: Chris Nauroth Assignee: Chris Nauroth
{{TestDFSClientExcludedNodes}} simulates failures of individual data nodes in the client's write pipeline and checks the client's ability to recover. HDFS-4246 added support for periodic "forgiveness" by caching the list of known bad data nodes with a periodic eviction. The test uses a 1 second cache expiration. This sometimes causes failed nodes to be forgiven too fast and violate the assumptions of the test. -- This message is automatically generated by JIRA.
