Hi All,
I want to provide version control for documents which I keep in HDFS. What I can do to attain this. Any ideas ?

HDFS is merely a filesystem today. You'll need to write your own
versioning layer on top of it if you need such a functionality.

HDFS is a filesystem that is designed to support map-reduce computation.
As such, the semantics differ from what SVN or GIT would want to have.
HBase provides versioned values. That might suffice for your needs.

Hi Ted,
Well in my case document size can be big, which is not good to keep in Hbase. So I rule out this option.

I'd imagine that you could point git or svn at HDFS mounted as regular
filesystem in user space (which works, but I've heard is a bit buggy). My
question is really what do you expect to gain by using HDFS this way (vs
NFS or a NAS filer for instance) ?

RE: Version control of files present in HDFSStuti Awasthi 2011-11-22, 06:11
Hey Chris,
This is what I also thought and looking at Mountable HDFS options. I need to check if its buggy.
To your other ques : I am building an app which will have TBs of data and require analysis. Now I am using HDFS as a background filesystem and Hbase for database option. To do analysis on the data, I use MR jobs .
All this is not provided by NFS. One part of this app include document management in which I wanted to provide version control. This is the usecase I have. May be this helps. ☺

HDFS is merely a filesystem today. You'll need to write your own versioning layer on top of it if you need such a functionality.

It is a bit off topic, but maprfs is closely equivalent to HDFS except that
it provides the read-write and NFS semantics you are looking for.
Trying to shoe-horn HDFS into a job that it wasn't intended to do (i.e.
general file I/O) isn't a great idea. Better to use what it is good for.

Re: Version control of files present in HDFSChris Shain 2011-11-22, 16:11
Agreed on HDFS not being designed for this purpose.
Additionally, version control tools are typically geared toward managing a
lot of small text files (e.g. source code) with lots of versions. The
versions are usually stored as diffs from a base version to conserve disk
space, and those diffs are re-applied to recreate any given file version.
If you are talking about a lot of very large files, a traditional version
control system may not be the most efficient option for a number of
reasons, not the least of which might be re-applying diffs to GB-sized
binary files. I'm not saying it wouldn't work, just that it really isn't
what VCS are usually designed for.
Simple snapshots of your file set, tar/gzipped, would probably be simpler
to manage. Creating a new (or for that matter retrieving and unpacking an
old) snapshot file could be a simple pre/post step in your MR job workflow.

Well the documents can be in various formats like pdf,doc,xls, video file,ppt etc and can vary in size from MBs to GBs.
I have read that if the file sizes are going bigger than MBs then it is not good to use Hbase for storage.
