Yiqun Lin commented on HDFS-11385:
----------------------------------
+1 for this idea. Attach a simple patch for this. Only one comment from me: Is
this should be an incompatible change? Because it will run ok when meeting the
failure.
> DistCp CopyCommitter should issue warning instead of throw exception when
> failed to delete file.

> CopyCommiter#deleteMissing(Configuration conf) does the following in a loop
> for all files that need to be deleted:
> {code}
> if (result) {
> LOG.info("Deleted " + trgtFileStatus.getPath() + " - Missing at
> source");
> deletedEntries++;
> } else {
> throw new IOException("Unable to delete " +
> trgtFileStatus.getPath());
> }
> {code}
> If for some reason there is a failure to delete a file, then an exception is
> thrown and no other files will be deleted.
> It seems more reasonable to issue a warning here instead of throw an
> exception.
