Subject [jira] Commented: (HADOOP-4044) Create symbolic links in HDFS

Tsz Wo (Nicholas), SZE commented on HADOOP-4044:
------------------------------------------------

bq. Good question. I prefer FsXxx, but we've not been consistent in Hadoop, nor is Java. I
think java.net.URL was a mistake, that it should have been named java.net.Url, that acronyms
in class names should be capitalized, not all caps. This makes them easier to parse.

It is the time to rename all the FSXxx classes since the pubic API is going to be changed
a lot in 0.20 anyway.

> HDFS should support symbolic links. A symbolic link is a special type of file that contains
a reference to another file or directory in the form of an absolute or relative path and that
affects pathname resolution. Programs which read or write to files named by a symbolic link
will behave as if operating directly on the target file. However, archiving utilities can
handle symbolic links specially and manipulate them directly.
