Siyao Meng updated HDFS-13870:
------------------------------
Description:
ALLOWSNAPSHOT, DISALLOWSNAPSHOT (since 2.8.0, HDFS-9057),
GETSNAPSHOTDIFF (since 3.0.3, HDFS-13052), GETSNAPSHOTTABLEDIRECTORYLIST
(HDFS-13141) don't have their API usage documentation in the [official
doc]([https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/WebHDFS.html)]
yet.
Below are my examples of those undocumented APIs:
{code:bash}
# ALLOWSNAPSHOT uses http method PUT.
curl -X "PUT"
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=ALLOWSNAPSHOT&user.name=hdfs"
# DISALLOWSNAPSHOT uses http method PUT.
curl -X "PUT"
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=DISALLOWSNAPSHOT&user.name=hdfs"
# GETSNAPSHOTDIFF uses GET.
curl
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=GETSNAPSHOTDIFF&user.name=hdfs&oldsnapshotname=snap1&snapshotname=snap2"
# GETSNAPSHOTTABLEDIRECTORYLIST uses GET.
curl
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=GETSNAPSHOTTABLEDIRECTORYLIST&user.name=hdfs"
{code}
was:
ALLOWSNAPSHOT, DISALLOWSNAPSHOT (since 2.8.0, HDFS-9057),
GETSNAPSHOTDIFF (since 3.0.3, HDFS-13052), GETSNAPSHOTTABLEDIRECTORYLIST
(HDFS-13141) don't have their API usage documentation in the [official
doc]([https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/WebHDFS.html)]

# DISALLOWSNAPSHOT uses http method PUT.
curl -X "PUT"
"<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=DISALLOWSNAPSHOT&user.name=hdfs"
# GETSNAPSHOTDIFF uses GET.
curl
"<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=GETSNAPSHOTDIFF&user.name=hdfs&oldsnapshotname=snap1&snapshotname=snap2"
# GETSNAPSHOTTABLEDIRECTORYLIST uses GET.
