Subject [jira] Issue Comment Edited: (HADOOP-5688) HftpFileSystem.getChecksum(..) does not work for the paths with scheme and authority
Date Thu, 16 Apr 2009 03:28:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699474#action_12699474

The problem is that HftpFileSystem does not construct the url correctly if the path contents
scheme and authority information.  For example
{code}
Path p = new Path("hftp://localhost:2750/foo");
FileSystem hftpfs = p.getFileSystem(conf);
FileChecksum cs = hftpfs.getFileChecksum(p); 
/*
The url constructed above will be
  http://localhost:2750/fileChecksumhftp://localhost:2750/filechecksum/foo?ugi=...
However, the correct url is
  http://localhost:2750/fileChecksum/foo?ugi=...
*/
{code}

> If a path with scheme and authority information (e.g. hftp://hostname:50070/foo.txt)
is passed to HftpFileSystem.getChecksum(..), it won't return the correct file checksum.
