Subject [jira] [Created] (HDFS-8151) Always use snapshot path as source when invalid snapshot names are used for diff based distcp
Date Wed, 15 Apr 2015 18:38:59 GMT
Jing Zhao created HDFS-8151:
-------------------------------

             Summary: Always use snapshot path as source when invalid snapshot names are used
for diff based distcp
                 Key: HDFS-8151
                 URL: https://issues.apache.org/jira/browse/HDFS-8151
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Jing Zhao
            Assignee: Jing Zhao
            Priority: Minor


HDFS-8036 makes the diff-based distcp use snapshot path as the source. This should also happen
when
# invalid snapshot names are provided as distcp parameters thus the diff report computation
on the target cluster fails
# there is modification happening in the target cluster thus {{checkNoChange}} returns false

In other cases like source and target FS are not DistributedFileSystem, we should throw exceptions.
