Colin Patrick McCabe created HDFS-4283: ------------------------------------------
Summary: Spurious Test failures in TestEditLog.testFuzzSequences Key: HDFS-4283 URL: https://issues.apache.org/jira/browse/HDFS-4283 Project: Hadoop HDFS Issue Type: Bug Components: test Affects Versions: 2.0.3-alpha Reporter: Colin Patrick McCabe Assignee: Colin Patrick McCabe Priority: Minor testFuzzSequences fails sometimes due to the additional UTF-8 validation added in HADOOP-9103. The issue is that the UTF8 class throws its exceptions as {{RuntimeExceptions}} rather than {{IOExceptions}}, and the fuzzing code is not expecting that. Example failure: {code} Failed org.apache.hadoop.hdfs.server.namenode.TestEditLog.testFuzzSequences Failing for the past 5 builds (Since Failed#3600 ) Took 4.8 sec.
