Description

In TestWriteToReplica and TestFsDatasetImpl, tests directly creates block and metadata files:

replicaInfo.getBlockFile().createNewFile();
replicaInfo.getMetaFile().createNewFile();

It leaks the implementation details of FsDatasetImpl. This JIRA proposes to use FsDatasetImplTestUtils (HDFS-9188) to create replicas.
