> During the test of OzoneFileSystem with spark I noticed ERROR messages
> multiple times:
> Something like this:
> {code}
> 2018-02-11 15:54:54 ERROR OzoneFileSystem:409 - Couldn't delete
> o3://bucket1.test/user/hadoop/.sparkStaging/application_1518349702045_0008 -
> does not exist
> {code}
> I checked the other implemetations, and they use DEBUG level. I think it's
> expected that the path sometimes points to a non-existing dir/file.
> To be consistent with the other implemetation I propose to lower the log
> level to debug.
> Examples from other file systems:
> S3AFileSystem:
> {code}
> } catch (FileNotFoundException e) {
> LOG.debug("Couldn't delete {} - does not exist", f);
> instrumentation.errorIgnored();
> return false;
> } catch (AmazonClientException e) {
> throw translateException("delete", f, e);
> }
> {code}
> Alyun:
> {code}
> try {
> return innerDelete(getFileStatus(path), recursive);
> } catch (FileNotFoundException e) {
> LOG.debug("Couldn't delete {} - does not exist", path);
> return false;
> }
> {code}
> SFTP:
> {code}
> } catch (FileNotFoundException e) {
> // file not found, no need to delete, return true
> return false;
> }
> {code}
> SwiftNativeFileSystem:
> {code}
> try {
> return store.delete(path, recursive);
> } catch (FileNotFoundException e) {
> //base path was not found.
> return false;
> }
> {code}
