Description

Do not expect hdfs dfs -ls s3a root to return error "No such file or directory" when the s3 bucket is empty. Expect no error and empty output, just like listing an empty directory.

$ hdfs dfs -ls s3a://jz-hdfs1/
Found 1 items
drwxrwxrwx   -          0 1969-12-31 16:00 s3a://jz-hdfs1/tmp
$ hdfs dfs -rmdir s3a://jz-hdfs1/tmp

$ hdfs dfs -ls s3a://jz-hdfs1/
ls: `s3a://jz-hdfs1/': No such file or directory
