[jira] [Created] (HDFS-9363) Add fetchReplica() to FsDatasetTestUtils()

Tony Wu created HDFS-9363:
-----------------------------

             Summary: Add fetchReplica() to FsDatasetTestUtils()
                 Key: HDFS-9363
                 URL: https://issues.apache.org/jira/browse/HDFS-9363
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: HDFS, test
    Affects Versions: 2.7.1
            Reporter: Tony Wu
            Assignee: Tony Wu
            Priority: Minor


{{FsDatasetTestUtils()}} abstracts away the details in {{FsDataset}} to allow writing generic tests regardless of underlying {{FsDataset}} implementations. We can add a {{fetchReplica()}} method to allow some HDFS tests to avoid using {{FsDatasetTestUtil#fetchReplicaInfo()}}, which assumes FsDatasetImpl is the only implementation of FsDataset.
