-------------------------------

             Summary: NPE while running Mover if the given path is for a file
                 Key: HDFS-7167
                 URL: https://issues.apache.org/jira/browse/HDFS-7167
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Jing Zhao
            Assignee: Jing Zhao


Thanks to [~prabushankar.c] for reporting this issue!

Currently in the new migration tool Mover, we allow users to specify a list of 
paths for migration. Then in {{Mover#processNamespace}} we directly call 
{{getFileInfo}} to retrieve the status of the given path. If the given path is 
a file, the returned HdfsFileStatus does not contain block location 
information, this can trigger an NPE.
