Subject [jira] Commented: (HDFS-1109) HFTP and URL Encoding
Date Tue, 23 Nov 2010 05:41:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934735#action_12934735

Dmytro Molkov commented on HDFS-1109:
-------------------------------------

Oh, this part is a bug, I never realized that in the web ui it was going after that url directly
instead of using the HFTP kind of call to the namenode to get redirected.
Should I open a JIRA to fix it? or do you want to reopen this one?

> We just saw this error happen in our cluster. If there is a file that has a "+" sign
in the name it is not readable through HFTP protocol.
> The problem is when we are reading a file with HFTP we are passing a name of the file
as a parameter in request and + gets undecoded into space on the server side. So the datanode
receiving the streamFile request tries to access a file with space instead of + in the name
and doesn't find that file.
> The proposed solution is to pass the filename as a part of URL as with all the other
HFTP commands, since this is the only place where it is not being treated this way. Are there
any objections to this?
