--------------------------------------
Summary: mkdir by file system shell fails on an empty bucket
Key: HADOOP-11742
URL: https://issues.apache.org/jira/browse/HADOOP-11742
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3
Environment: CentOS 7
Reporter: Takenori Sato
I have built the latest 2.7, and tried S3AFileSystem.
Then found that _mkdir_ fails on an empty bucket, named *s3a* here, as follows:
{code}
# hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -mkdir s3a://s3a/foo
15/03/24 03:49:35 DEBUG s3a.S3AFileSystem: Getting path status for
s3a://s3a/foo (foo)
15/03/24 03:49:36 DEBUG s3a.S3AFileSystem: Not Found: s3a://s3a/foo
15/03/24 03:49:36 DEBUG s3a.S3AFileSystem: Getting path status for s3a://s3a/ ()
15/03/24 03:49:36 DEBUG s3a.S3AFileSystem: Not Found: s3a://s3a/
mkdir: `s3a://s3a/foo': No such file or directory
{code}
So does _ls_.
{code}
# hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -ls s3a://s3a/
15/03/24 03:47:48 DEBUG s3a.S3AFileSystem: Getting path status for s3a://s3a/ ()
15/03/24 03:47:48 DEBUG s3a.S3AFileSystem: Not Found: s3a://s3a/
ls: `s3a://s3a/': No such file or directory
{code}
This is how it works via s3n.
{code}
# hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -ls s3n://s3n/
# hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -mkdir s3n://s3n/foo
# hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -ls s3n://s3n/
Found 1 items
drwxrwxrwx - 0 1970-01-01 00:00 s3n://s3n/foo
{code}
The snapshot is the following:
