    Description

      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
