Yongjun Zhang updated HDFS-12139:
---------------------------------
Attachment: HDFS-12139.002.patch
> HTTPFS liststatus returns incorrect pathSuffix for path of file
> ---------------------------------------------------------------
>
> Key: HDFS-12139
> URL: https://issues.apache.org/jira/browse/HDFS-12139
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: httpfs
> Reporter: Yongjun Zhang
> Assignee: Yongjun Zhang
> Attachments: HDFS-12139.001.patch, HDFS-12139.002.patch
>
>
> Per the following logs, we can see that liststatus returns the same
> pathSuffix "test.txt" for /tmp/yj/yj1 and /tmp/yj/yj1/test.txt, which is
> wrong. The pathSuffix for the latter should be empty.
> {code}
> [thost ~]$ hadoop fs -copyFromLocal test.txt /tmp/yj/yj1
> [thost ~]$ curl
> "http://thost.x.y:14000/webhdfs/v1/tmp/yj/yj1?op=LISTSTATUS&user.name=tuser";
> {"FileStatuses":{"FileStatus":[{"pathSuffix":"test.txt","type":"FILE","length":16,"owner":"tuser","group":"supergroup","permission":"644","accessTime":1500007684989,"modificationTime":1500007685286,"blockSize":134217728,"replication":3}]}}
> [thost ~]$ curl
> "http://thost.x.y:14000/webhdfs/v1/tmp/yj/yj1/test.txt?op=LISTSTATUS&user.name=tuser";
> {"FileStatuses":{"FileStatus":[{"pathSuffix":"test.txt","type":"FILE","length":16,"owner":"tuser","group":"supergroup","permission":"644","accessTime":1500007684989,"modificationTime":1500007685286,"blockSize":134217728,"replication":3}]}}
> {code}
> Due to this bug, the symptom of running distcp with httpfs to copy a single
> file /tmp/test.txt is:
> {quote}
> WARN org.apache.hadoop.security.UserGroupInformation:
> PriviledgedActionException as:systest (auth:PROXY) via httpfs (auth:SIMPLE)
> cause:org.apache.hadoop.security.AccessControlException: Permission denied:
> user=systest, access=EXECUTE,
> inode="/tmp/test.txt":systest:supergroup:-rw-r--r-- (Ancestor /tmp/test.txt
> is not a directory).
> {quote}
> because /tmp/test.txt is treated as /tmp/test.txt/test.txt.
