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.
