[jira] [Created] (HIVE-20476) REPL LOAD and EXPORT/IMPORT operations ignores distcp failures.

Sankar Hariappan created HIVE-20476:
---------------------------------------

             Summary: REPL LOAD and EXPORT/IMPORT operations ignores distcp failures.
                 Key: HIVE-20476
                 URL: https://issues.apache.org/jira/browse/HIVE-20476
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2, repl
    Affects Versions: 3.1.0
            Reporter: Sankar Hariappan
            Assignee: Sankar Hariappan


CopyUtils uses FileUtils.distCp to copy files but doesn't check the return value. It returns false if the copy fails.
Now, REPL LOAD and EXPORT/IMPORT commands internally uses CopyUtils to copy data files across clusters and here it may return success even if file copy fails and may cause data loss.

Need to throw error and retry.
