我有一个名称节点，其fsimage损坏了，并且只有一个fsimage可用。我有secondarynamenode具有可用的检查点。
现在，我想将Checkpoint导入一个新目录。
旧目录：cd /home/rakeshbharadwaj/Desktop/hadoop-2.7.4-ex2/nn
新目录：我已在hdfs-site.xml中将其更改为/home/rakeshbharadwaj/Desktop/hadoop-2.7.4-ex2/new
我尝试运行hdfs namenode importcheckPoint，它给了我以下错误
19/02/26 12:38:51 INFO common.Storage: Lock on /home/rakeshbharadwaj/Desktop/hadoop-2.7.4-ex2/new/in_use.lock acquired by nodename 5270@rakeshbharadwaj-VirtualBox

因此，我已经通过运行hdfs namenode -format格式化了namenode。格式成功。格式化之后，形成了新图像 fsimage_0000000000000000000
现在，我再次运行hdfs namenode -importCheckpoint，它给了我以下错误。
19/02/26 12:30:47 WARN namenode.FSNamesystem: Encountered exception loading fsimage

问题：如何解决这个问题并从新目录中的检查点获取fsimage。
