Akira Ajisaka commented on HDFS-13972:
--------------------------------------
Thanks [~crh] for the 003 patch. Mostly works fine, but WebHDFS liststatus
couldn't list the mount point correctly in my environment.
Using HDFS API, two directory are listed.
{noformat}
$ hdfs dfs -ls hdfs://<router>:8888/tmp/
Found 2 items
drwxrwxrwx - hdfs supergroup 0 2018-11-09 17:50
hdfs://<router>:8888/tmp/tmp1
drwxrwxrwx - hdfs supergroup 0 2018-11-09 17:50
hdfs://<router>:8888/tmp/tmp2
{noformat}
Using WebHDFS API, only one directory is listed.
{noformat}
$ curl -u : --negotiate -i "http://<router>:50071/webhdfs/v1/tmp/?op=LISTSTATUS"
(snip)
{"FileStatuses":{"FileStatus":[
{"accessTime":0,"blockSize":0,"childrenNum":0,"fileId":16387,"group":"supergroup","length":0,"modificationTime":1552016766769,"owner":"hdfs","pathSuffix":"tmp1","permission":"755","replication":0,"storagePolicy":0,"type":"DIRECTORY"}
]}}
{noformat}
The mount table is as follows:
{noformat}
$ hdfs dfsrouteradmin -ls /tmp
Mount Table Entries:
Source Destinations Owner
Group Mode Quota/Usage
/tmp ns1->/tmp aajisaka
users rwxr-xr-x [NsQuota: -/-, SsQuota: -/-]
/tmp/tmp1 ns1->/tmp/tmp1 aajisaka
users rwxr-xr-x [NsQuota: -/-, SsQuota: -/-]
/tmp/tmp2 ns2->/tmp/tmp2 aajisaka
