-----------------------------------

             Summary: Change TestFileTruncate to FsDatasetTestUtils to get block file size and genstamp.
                 Key: HDFS-9252
                 URL: https://issues.apache.org/jira/browse/HDFS-9252
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.7.1
            Reporter: Lei (Eddy) Xu
            Assignee: Lei (Eddy) Xu


{{TestFileTruncate}} verifies block size and genstamp by directly accessing the  local filesystem, e.g.:

{code}
assertTrue(cluster.getBlockMetadataFile(dn0,
   newBlock.getBlock()).getName().endsWith(
   newBlock.getBlock().getGenerationStamp() + ".meta"));
{code}

Lets abstract the fsdataset-special logic behind FsDatasetTestUtils.
