Aaron T. Myers commented on HDFS-5289: -------------------------------------- Thanks a lot for the review, Todd. I'm quite confident that the test failure is unrelated. I'm going to commit this momentarily. > Race condition in TestRetryCacheWithHA#testCreateSymlink causes spurious test > failure > ------------------------------------------------------------------------------------- > > Key: HDFS-5289 > URL: https://issues.apache.org/jira/browse/HDFS-5289 > Project: Hadoop HDFS > Issue Type: Bug > Components: test > Affects Versions: 2.1.1-beta > Reporter: Aaron T. Myers > Assignee: Aaron T. Myers > Attachments: HDFS-5289.patch > > > The code to check if the operation has been completed on the active NN can > potentially execute before the thread actually doing the operation has run. > In this case the checking code will retry the check if the result of the > check is null. However, the test operation does not in fact return null, > instead throwing an exception if the file doesn't exist yet. We need to catch > the exception and retry. -- This message was sent by Atlassian JIRA (v6.1#6144)
