> 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}}.
