---------------------------------------
Summary: remove magic directory skipping from CopyTask
Key: HIVE-19279
URL: https://issues.apache.org/jira/browse/HIVE-19279
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Follow up from HIVE-17657.
Code exists in copytask that copies files (fancy that); however, when listing
the files, if a single directory exists at the source with no other files, it
will skip the directory and copy the files inside instead.
This directory in various tests happens to be the "data" directory from export,
or some random partition directory ("foo=bar") that if not skipped makes it
into the real partition directory at the destination.
It won't do that if any other files or directories are present.
This seems brittle. Caller of the CopyTask should specify exactly what it wants
copied instead of relying on this behavior.
