Aaron T. Myers resolved HDFS-2433. ---------------------------------- Resolution: Cannot Reproduce I don't think I've seen this fail in a long, long time. Going to close this out. Please reopen if you disagree. > TestFileAppend4 fails intermittently > ------------------------------------ > > Key: HDFS-2433 > URL: https://issues.apache.org/jira/browse/HDFS-2433 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode, namenode, test > Affects Versions: 0.20.205.0, 1.0.0 > Reporter: Robert Joseph Evans > Priority: Critical > Attachments: failed.tar.bz2 > > > A Jenkins build we have running failed twice in a row with issues form > TestFileAppend4.testAppendSyncReplication1 in an attempt to reproduce the > error I ran TestFileAppend4 in a loop over night saving the results away. > (No clean was done in between test runs) > When TestFileAppend4 is run in a loop the testAppendSyncReplication[012] > tests fail about 10% of the time (14 times out of 130 tries) They all fail > with something like the following.
