Subject [Hadoop Wiki] Update of "HCFS" by SteveWatt
Date Mon, 22 Apr 2013 23:57:05 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "HCFS" page has been changed by SteveWatt:
http://wiki.apache.org/hadoop/HCFS

New page:
'''Hadoop Compatible File Systems (HCFS)'''

Hadoop Core provides a plugin architecture for FileSystems that provides the ability to configure
Hadoop to use other File Systems besides HDFS. One example of this is the Hadoop Amazon S3
Plugin, which exposes the Amazon S3 Service as a Hadoop Compatible File System allowing any
client of Hadoop Core (such as MapReduce and HBase) to seamlessly run on top of S3.

''How is this done?''

Begin with the Abstract FileSystem explanation (todo). Point to [[https://issues.apache.org/jira/browse/HADOOP-9371|
Defining the Semantics of the Hadoop FileSystem more rigorously]]. Mention the work unwiring
Ambari from being exclusively HDFS. [[https://issues.apache.org/jira/browse/HADOOP-9258| Better
testing for HCFS]]
