webhdfs: a complete FileSystem implementation for accessing HDFS over HTTP
--------------------------------------------------------------------------

Key: HDFS-2316
URL: https://issues.apache.org/jira/browse/HDFS-2316
Project: Hadoop HDFS
Issue Type: New Feature
Reporter: Tsz Wo (Nicholas), SZE
Assignee: Tsz Wo (Nicholas), SZE


We current have hftp for accessing HDFS over HTTP. However, hftp is a read-only FileSystem and does not provide "write" accesses.

In HDFS-2284, we propose to have webhdfs for providing a complete FileSystem implementation for accessing HDFS over HTTP. The is the umbrella JIRA for the tasks.

    --------------------------------------


    we are using an enum {FILE, DIRECTORY, SYMLINK} for the FileStatus, but the constructor of FileStatus, for symlinks, takes a isDir boolean.

    This means we are losing the isFile/isDir information in the case of symlinks but it seems that the HDFS implementation keeps that.

    If this is the case, we should add that info either as a new enum set or instead using enum using 2 booleans.

    symlinks already return false for isDir, not an issue.
