Ted Yu commented on HBASE-19969:
--------------------------------
{code}
+ if (!fs.delete(destPath, true)) {
+ System.out.println("Failed to delete " + destPath);
+ }
+ boolean res = fs.rename(tmpPath, destPath);
{code}
As I said previously, if the delete() call fails, the rename() would fail as
well.
I think IOE can be thrown for both failures.
getBackupTmpDirForBackupId is no longer in the patch. Can you describe related
changes ?

> Some file system operations are not fault tolerant during merge. We delete
> backup data in a backup file system, then copy new data over to backup
> destination. Deletes can be partial, copy can fail as well
