Íñigo Goiri commented on HDFS-13673: ------------------------------------ Yes, I have been seeing it in the past. However, I think it would be good to fix it before committing this JIRA to make sure. There has been a bunch of JIRAs in the past for this: HDFS-2434, HDFS-3812, HDFS-4338, HDFS-4355 Actually, HDFS-6126 is still open. Can you check if you cna find why it is flaky? If so, we may be able to use HDFS-6126. > TestNameNodeMetrics fails on Windows > ------------------------------------ > > Key: HDFS-13673 > URL: https://issues.apache.org/jira/browse/HDFS-13673 > Project: Hadoop HDFS > Issue Type: Bug > Components: test > Affects Versions: 3.1.0, 2.9.1 > Reporter: Zuoming Zhang > Assignee: Zuoming Zhang > Priority: Minor > Labels: Windows > Fix For: 3.1.0, 2.9.1 > > Attachments: HDFS-13673.000.patch, HDFS-13673.001.patch, > TestNameNodeMetrics-testVolumeFailures-Report.000.txt, > TestNameNodeMetrics-testVolumeFailures-Report.001.txt > > > _TestNameNodeMetrics_ fails on Windows > > Problem: > This is because in _testVolumeFailures_, it tries to call > _DataNodeTestUtils.injectDataDirFailure_ on a volume folder. What > _injectDataDirFailure_does is actually modifying the folder name from > _volume_name_ to _volume_name_._origin_ and create a new file named as > _volume_name_. Inside the folder, it has two things: 1. a directory named as > "_current_", 2. a file named as "_in_use.lock_". Windows behaves different > from Linux when renaming the parent folder of a locked file. Windows prevent > you from renaming while Linux allows. > Fix: > So in order to inject data failure on to the volume. Instead of renaming the > volume folder itself. Rename the folder inside it which doesn't hold a lock. > Since the folder inside the volume is "_current_". Then we only need to > inject data failure to _volume_name/current_. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
