Yiqun Lin created HDFS-10388: -------------------------------- Summary: DistributedFileSystem#getStatus returns a misleading FsStatus Key: HDFS-10388 URL: https://issues.apache.org/jira/browse/HDFS-10388 Project: Hadoop HDFS Issue Type: Bug Components: fs Affects Versions: 2.7.1 Reporter: Yiqun Lin Assignee: Yiqun Lin
The method {{DistributedFileSystem#getStatus}} returns the dfs's disk status. {code} public FsStatus getStatus(Path p) throws IOException { statistics.incrementReadOps(1); return dfs.getDiskStatus(); } {code} So the param path is no meaning here. And the object returned will mislead for users to use this method. I looked into the code, only when the file system has multiple partitions, the use and capacity of the partition pointed to by the specified path will be reflected. For example, in the subclass {{RawLocalFileSystem}}, it will be return correctly. We should return a new meaningless FsStatus here (like new FsStatus(0, 0, 0))and indicated that the invoked method isn't available in {{DistributedFileSystem}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
