Hi Jagadeesh,
I am very much new to Hadoop and would like to know some details about the
reliability and stability. I am developing flickr kind of an application for
storing and sharing movies and would like to use Hadoop as my storage
backend. I am planning to put in atleast 100 nodes and would like to know
more about the product. I will appreciate if you could answer some of my
queries.
This is a very interesting application for Hadoop.
Did you have any progress with the system?
1. Is the product matured enough for using in an application like this?
Yes.
2. Has somebody tested it using atleast 100 nodes?
Yes, there are even larger installations.
3. Can I have multiple master nodes in Hadoop to do load balancing and
fail-overs?
Not yet.
4. What is the maximum number of simultaneous connections possible in
Hadoop?
Hadoop is designed to support and actually supports high volume of
simultaneous connections.
E.g., on a 100 node cluster an extensive map-reduce job can generate 400
concurrent connections.
Creation time and date is not implemented for DFS files.
Do you have a good application for ctime?
Thank you,
--Konstantin
