             Summary: Ozone: Unit tests running failed in Windows
                 Key: HDFS-11619
                 URL: https://issues.apache.org/jira/browse/HDFS-11619
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin


The unit tests runs failed in Windows. The stack infos in my local when I ran the test {{TestAllocateContainer#testAllocate}}:
{code}
java.nio.file.InvalidPathException: Illegal char <:> at index 2: /D:/work-project/hadoop/hadoop-hdfs-project/hadoop-hdfs/target/test-classes/org/apache/hadoop/ozone/MiniOzoneCluster2f590eac-54a9-4f7d-9f91-911090d581aa\d54f6948-ea8c-4ade-8fa2-4b7bf849ed87\scm

	at org.apache.hadoop.ozone.scm.TestAllocateContainer.init(TestAllocateContainer.java:54)
{code}
The root cause of the failure is that the path generated for the scm is not a valid path. We should replace the following related code in {{MiniOzoneCluster.Builder#Builder()}}.
{code}
      URL p = conf.getClass().getResource("");
      path = p.getPath().concat(MiniOzoneCluster.class.getSimpleName() + UUID
          .randomUUID().toString());
{code}
One way maybe we can use {{GenericTestUtils#getTempPath}} to replace with it.
