             Summary: HttpFS: LISTSTATUS result is missing some fields for each entry
                 Key: HDFS-14665
                 URL: https://issues.apache.org/jira/browse/HDFS-14665
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Siyao Meng


WebHDFS:
{code:java}
GET /webhdfs/v1/tmp/?op=LISTSTATUS&user.name=hdfs HTTP/1.1
{code}
{code}
{
  "FileStatuses": {
    "FileStatus": [
...
      {
        "accessTime": 0,
        "blockSize": 0,
        "childrenNum": 0,
        "fileId": 16395,
        "group": "hadoop",
        "length": 0,
        "modificationTime": 1563893395614,
        "owner": "mapred",
        "pathSuffix": "logs",
        "permission": "1777",
        "replication": 0,
        "storagePolicy": 0,
        "type": "DIRECTORY"
      }
    ]
  }
}
{code}
HttpFS:
{code:java}
GET /webhdfs/v1/tmp/?op=LISTSTATUS&user.name=hdfs HTTP/1.1
{code}
{code}
{
  "FileStatuses": {
    "FileStatus": [
...
      {
        "pathSuffix": "logs",
        "type": "DIRECTORY",
        "length": 0,
        "owner": "mapred",
        "group": "hadoop",
        "permission": "1777",
        "accessTime": 0,
        "modificationTime": 1563893395614,
        "blockSize": 0,
        "replication": 0
      }
    ]
  }
}
{code}
You can see the same LISTSTATUS request to HttpFS is missing childrenNum (directories only I guess), fileId and storagePolicy fields. The same applies to LISTSTATUS_BATCH, which might be using the same underlying calls to compose the response.

Also may file another Jira to align the order of the keys in the responses.
