org.apache.hadoop.hdfs.server.namenode.FsImageValidation

public class FsImageValidation
extends java.lang.Object

For validating FSImage. This tool will load the user specified FSImage, build the namespace tree, and then run validations over the namespace tree. The main difference of this tool and OfflineImageViewer is that OfflineImageViewer only loads FSImage but it does not build the namespace tree. Therefore, running validations over the namespace tree is impossible in OfflineImageViewer.
