[jira] [Commented] (HADOOP-7257) A client side mount table to give per-application/per-job file system view

["Ravi Prakash (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-7257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13135063#comment-13135063 ] 

Ravi Prakash commented on HADOOP-7257:
--------------------------------------

@Sanjay: ViewFs.java:624
{noformat}
    static private void checkPathIsSlash(final Path f) throws IOException {
      if (f != InodeTree.SlashPath) {
        throw new IOException (
        "Internal implementation error: expected file name to be /" );
      }
    }
{noformat}

Should the condition be 
{noformat}
if (f.equals(Inode.SlashPath)
{noformat}

My small program
{noformat}
	Path p = new Path("/");
	Path q = new Path("/");
	System.out.println("Equals? " + (p == q) );
{noformat}
Prints "Equals? false"
