[jira] [Updated] (HDFS-15376) Fix POST and PUT errors in httpfs
documentation
[ https://issues.apache.org/jira/browse/HDFS-15376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
bianqi updated HDFS-15376:
--------------------------
Description:
In the official Hadoop documentation, there is an exception when executing the following command.
{quote} {{curl -X POST 'http://httpfs-host:14000/webhdfs/v1/user/foo/bar?op=MKDIRS&user.name=foo'}} creates the HDFS {{/user/foo/bar}} directory.
{quote}
Command line returns results：
{quote} *{"RemoteException":{"message":"Invalid HTTP POST operation [MKDIRS]","exception":"IOException","javaClassName":"java.io.IOException"}}*
{quote}
I checked the source code and found that the way to create the file should use PUT to submit the form.
I modified to execute the command in PUT mode and got the result as follows
{quote} {{curl -X POST 'http://httpfs-host:14000/webhdfs/v1/user/foo/bar?op=MKDIRS&user.name=foo'}} creates the HDFS {{/user/foo/bar}} directory.
{quote}
Command line returns results：
{quote}{"boolean":true}
{quote}
At the same time the folder is created successfully.
