tomscut created HDFS-16503: ------------------------------ Summary: 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 Attachments: image-2022-03-14-09-35-49-860.png
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, the first step returns success, but the second step throws an {*}InvalidPathException{*}. 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-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
