Subject [jira] [Created] (HDFS-9188) Make block corruption related tests FsDataset-agnostic.
Date Thu, 01 Oct 2015 21:23:26 GMT
Lei (Eddy) Xu created HDFS-9188:

             Summary: Make block corruption related tests FsDataset-agnostic. 
                 Key: HDFS-9188
                 URL: https://issues.apache.org/jira/browse/HDFS-9188
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: HDFS, test
    Affects Versions: 2.7.1
            Reporter: Lei (Eddy) Xu
            Assignee: Lei (Eddy) Xu

Currently, HDFS does block corruption tests by directly accessing the files stored on the
storage directories, which assumes {{FsDatasetImpl}} is the dataset implementation. However,
with works like OZone (HDFS-7240) and HDFS-8679, there will be different FsDataset implementations.

So we need a general way to run whitebox tests like corrupting blocks and crc files.
