Alejandro Abdelnur updated HDFS-2178:
-------------------------------------
Attachment: HDFS-2178.patch
Corrected patch updated (my MacOS FileSystem is case-insensitive and the rename
to uppercase FS failed from a Fs typo-ed failed). Also, remove unnecessary
Maven repos from root POM. Trimmed trailing spaces in files in patch. Removed
commented code in TestWebhdfsFileSsytem class.
Following up the 'pure proxy' comment, Hoop also can proxy viewfs (with the
mapping table in hoop instead of the client), thing that (IMU) webhdfs cannot
no. Technically we could move Hoop under common. But Hoop depends on HDFS for
testing which it may be seen as a circular dependency (i'm saying may because
in practice it is not, but module dir organization would suggest that).

> We'd like to contribute Hoop to Hadoop HDFS as a replacement (an improvement)
> for HDFS Proxy.
> Hoop provides access to all Hadoop Distributed File System (HDFS) operations
> (read and write) over HTTP/S.
> The Hoop server component is a REST HTTP gateway to HDFS supporting all file
> system operations. It can be accessed using standard HTTP tools (i.e. curl
> and wget), HTTP libraries from different programing languages (i.e. Perl,
> Java Script) as well as using the Hoop client. The Hoop server component is a
> standard Java web-application and it has been implemented using Jersey
> (JAX-RS).
> The Hoop client component is an implementation of Hadoop FileSystem client
> that allows using the familiar Hadoop filesystem API to access HDFS data
> through a Hoop server.

> Hoop is a Maven based project that depends on Hadoop HDFS and Alfredo (for
> Kerberos HTTP SPNEGO authentication).
> To make the integration easy, HDFS Mavenization (HDFS-2096) would have to be
> done first, as well as the Alfredo contribution (HADOOP-7119).
