Tony Wu updated HDFS-9308:
--------------------------
Attachment: HDFS-9308.003.patch
In v3 patch:
* Addressed [~eddyxu]'s review comments.
*Please note:*
{{TestCrcCorruption#testCrcCorruption}} seems to be broken by
43539b5ff4ac0874a8a454dc93a2a782b0e0ea8f for HDFS-4937 (did a quick binary
search to find this change). I will open a separate JIRA for the test failure.
Manually applied the patch to before the change and verified it works:

> HDFS-9188 introduced {{corruptMeta()}} method to make corrupting the metadata
> file filesystem agnostic. There should also be a {{truncateMeta()}} and
> {{deleteMeta()}} method in MiniDFSCluster to allow truncation of metadata
> files on DataNodes without writing code that's specific to underling file
> system. {{FsDatasetTestUtils#truncateMeta()}} is already implemented by
> HDFS-9188 and cam be exposed easily in {{MiniDFSCluster}}.
> This will be useful for tests such as
> {{TestLeaseRecovery#testBlockRecoveryWithLessMetafile}} and
> {{TestCrcCorruption#testCrcCorruption}}.
