[jira] [Created] (HADOOP-13626) Remove distcp dependency on
FileStatus serialization
Chris Douglas created HADOOP-13626:
--------------------------------------
Summary: Remove distcp dependency on FileStatus serialization
Key: HADOOP-13626
URL: https://issues.apache.org/jira/browse/HADOOP-13626
Project: Hadoop Common
Issue Type: Bug
Components: tools/distcp
Reporter: Chris Douglas
DistCp uses an internal struct {{CopyListingFileStatus}} to record metadata. Because this record extends {{FileStatus}}, it also relies on the {{Writable}} contract from that type. Because DistCp performs its checks on a subset of the fields (i.e., does not actually rely on {{FileStatus}} as a supertype), these types should be independent.
