Ayush Saxena resolved HDFS-16503. --------------------------------- Fix Version/s: 3.4.0 Hadoop Flags: Reviewed Resolution: Fixed > Should verify whether the path name is valid in the WebHDFS > ----------------------------------------------------------- > > Key: HDFS-16503 > URL: https://issues.apache.org/jira/browse/HDFS-16503 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: tomscut > Assignee: tomscut > Priority: Major > Labels: pull-request-available > Fix For: 3.4.0 > > Attachments: image-2022-03-14-09-35-49-860.png > > Time Spent: 1h 50m > Remaining Estimate: 0h > > When creating a file using WebHDFS, there are two main steps: > 1. 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
