Siyao Meng updated HDFS-13870:
------------------------------
Description:
Adding ALLOWSNAPSHOT and DISALLOWSNAPSHOT (since 2.8.0, HDFS-9057) to WebHDFS
REST API
[doc|https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/WebHDFS.html].
Below are my examples of the APIs:
{code:bash}
# ALLOWSNAPSHOT uses http method PUT.
curl -X "PUT"
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=ALLOWSNAPSHOT&user.name=hdfs"
Response on success:
HTTP/1.1 200 OK
Content-Type: application/octet-stream
{code}
{code:bash}
# DISALLOWSNAPSHOT uses http method PUT.
curl -X "PUT"
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=DISALLOWSNAPSHOT&user.name=hdfs"
Response on success:
HTTP/1.1 200 OK
Content-Type: application/octet-stream
{code}
Note: GETSNAPSHOTDIFF and GETSNAPSHOTTABLEDIRECTORYLIST are already documented.
{code:bash}
# GETSNAPSHOTDIFF uses GET.
curl
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=GETSNAPSHOTDIFF&user.name=hdfs&oldsnapshotname=snap1&snapshotname=snap2"
Response on success (example):
HTTP/1.1 200 OK
Content-Type: application/json
{"SnapshotDiffReport":{"diffList":[{"sourcePath":"","type":"MODIFY"},{"sourcePath":"newfile.txt","type":"CREATE"}],"fromSnapshot":"snapOld","snapshotRoot":"/snaptest","toSnapshot":"snapNew"}}
{code}
{code:bash}
# GETSNAPSHOTTABLEDIRECTORYLIST uses GET.
curl
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=GETSNAPSHOTTABLEDIRECTORYLIST&user.name=hdfs"
Response on success (example):
HTTP/1.1 200 OK
Content-Type: application/json
{"SnapshottableDirectoryList":[{"dirStatus":{"accessTime":0,"blockSize":0,"childrenNum":0,"fileId":16392,"group":"supergroup","length":0,"modificationTime":1535151813500,"owner":"hdfs","pathSuffix":"snaptest","permission":"755","replication":0,"storagePolicy":0,"type":"DIRECTORY"},"parentFullPath":"/","snapshotNumber":2,"snapshotQuota":65536}]}
{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]
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"
Response on success:
HTTP/1.1 200 OK
Content-Type: application/octet-stream
{code}
{code:bash}
# DISALLOWSNAPSHOT uses http method PUT.
curl -X "PUT"
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=DISALLOWSNAPSHOT&user.name=hdfs"
Response on success:
HTTP/1.1 200 OK
Content-Type: application/octet-stream
{code}
{code:bash}
# GETSNAPSHOTDIFF uses GET.
curl
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=GETSNAPSHOTDIFF&user.name=hdfs&oldsnapshotname=snap1&snapshotname=snap2"
Response on success (example):
HTTP/1.1 200 OK
Content-Type: application/json
{"SnapshotDiffReport":{"diffList":[{"sourcePath":"","type":"MODIFY"},{"sourcePath":"newfile.txt","type":"CREATE"}],"fromSnapshot":"snapOld","snapshotRoot":"/snaptest","toSnapshot":"snapNew"}}
{code}
{code:bash}
# GETSNAPSHOTTABLEDIRECTORYLIST uses GET.
curl
"http://<SERVER>:<PORT>/webhdfs/v1/snaptest/?op=GETSNAPSHOTTABLEDIRECTORYLIST&user.name=hdfs"
Response on success (example):
HTTP/1.1 200 OK
Content-Type: application/json
{"SnapshottableDirectoryList":[{"dirStatus":{"accessTime":0,"blockSize":0,"childrenNum":0,"fileId":16392,"group":"supergroup","length":0,"modificationTime":1535151813500,"owner":"hdfs","pathSuffix":"snaptest","permission":"755","replication":0,"storagePolicy":0,"type":"DIRECTORY"},"parentFullPath":"/","snapshotNumber":2,"snapshotQuota":65536}]}
