[jira] [Assigned] (HDFS-17528) FsImageValidation: set txid when saving a new image

     [ https://issues.apache.org/jira/browse/HDFS-17528?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tsz-wo Sze reassigned HDFS-17528:
---------------------------------

    Component/s: tools
       Assignee: Tsz-wo Sze
    Description: 
- When the fsimage is specified as a file and the FsImageValidation tool saves a new image (for removing inaccessible inodes), the txid is not set.  Then, the resulted image will have 0 as its txid.

- When the fsimage is specified as a directory, the txid is set.  However, it will get NPE since NameNode metrics is uninitialized (although the metrics is not used by FsImageValidation).
