> breakHardlinks() of ReplicaInfo(branch-2)/LocalReplica(trunk) replaces file while the source is still opened as input stream, which will fail and throw exception on Windows. It's the cause of unit test case org.apache.hadoop.hdfs.TestFileAppend#testBreakHardlinksIfNeeded failure on Windows.
> Other test cases of TestFileAppend fail randomly on Windows due to sharing the same test folder, and the solution is using randomized base dir of MiniDFSCluster via HDFS-13408
