Todd Lipcon updated HDFS-2525: ------------------------------ Fix Version/s: 2.0.0-alpha 0.23.2 Setting fix versions - this was included in the 2.0.0 release as well as 0.23.2 > Race between BlockPoolSliceScanner and append > --------------------------------------------- > > Key: HDFS-2525 > URL: https://issues.apache.org/jira/browse/HDFS-2525 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode > Affects Versions: 0.23.0, 0.24.0 > Reporter: Todd Lipcon > Assignee: Brandon Li > Priority: Critical > Fix For: 0.23.2, 2.0.0-alpha > > Attachments: HDFS-2525-branch-0.23.patch, HDFS-2525.patch > > > I wrote a test which runs append() in a loop on a single file with a single > replica, appending 0~100 bytes each time. If this races with the > BlockPoolSliceScanner, I observe the BlockPoolSliceScanner getting FNFE, then > reporting the block as bad to the NN. This causes the writer thread to loop > forever on completeFile() since it doesn't see a valid replica. -- This message is automatically generated by JIRA.
