[jira] [Created] (HDFS-9308) Add truncateMeta() to MiniDFSCluster

Tony Wu created HDFS-9308:
-----------------------------

             Summary: Add truncateMeta() to MiniDFSCluster
                 Key: HDFS-9308
                 URL: https://issues.apache.org/jira/browse/HDFS-9308
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: HDFS, test
    Affects Versions: 2.7.1
            Reporter: Tony Wu
            Assignee: Tony Wu
            Priority: Minor


HDFS-9188 introduced {{corruptMeta()}} method to make corrupting the metadata file filesystem agnostic. There should also be a {{truncateMeta()}} method to allow truncation of metadata files on DataNodes without writing code that's specific to underling file system. 

This will be useful for tests such as {{TestLeaseRecovery#testBlockRecoveryWithLessMetafile}}.
