Subject [jira] [Commented] (HDFS-3000) Add a public API for setting quotas
Date Tue, 03 Apr 2012 02:10:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3000?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13244921#comment-13244921
] 

Tsz Wo (Nicholas), SZE commented on HDFS-3000:
----------------------------------------------

> I tried to do this, but it's not as easy as it seems since DistributedFileSystem is taking
care of a bunch of path handling. ... are you OK leaving it as is, Nicholas?

Sure.  If it is too hard, let's leave it for now and make the improvement later.

+1 patch looks good.  Some minor comments which could be fixed here or later.

- "quota (count of files and directories)" => "namespace quota (count of name objects including
files, directories and symlinks)"

- "space quota (size of files and directories) for a directory." => "disk space quota (size
of files) for a directory.  Note that directories and symlinks do not occupy disk space.

- You may want to put the following in one line.
{code}
 public HdfsAdmin(URI uri, Configuration conf)
      throws IOException {
{code}

- Remove "throws IOException" from TestHdfsAdmin.shutDownCluster().

> Currently one can set the quota of a file or directory from the command line, but if
a user wants to set it programmatically, they need to use DistributedFileSystem, which is
annotated InterfaceAudience.Private.
