Obtain the location of the Datanode to be written. > 2. Put the file to this location. > Currently *NameNodeRpcServer* verifies that pathName is valid, but > *NamenodeWebHdfsMethods* and *RouterWebHdfsMethods* do not. > So if we use an invalid path(such as duplicated slash), the first step > returns success, but the second step throws an {*}InvalidPathException{*}. > IMO, we should also do the validation in WebHdfs, which is consistent with > the NameNodeRpcServer. > !image-2022-03-14-09-35-49-860.png|width=548,height=164! > The same webHDFS operations are: CREATE, APPEND, OPEN, GETFILECHECKSUM. So we > can add DFSUtil.isValidName to redirectURI for *NamenodeWebHdfsMethods* and > *RouterWebHdfsMethods.* -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
