---------------------------------------
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.
