Hi Mohammad,
I believe we've already answered this earlier to an almost exact question:
http://search-hadoop.com/m/b8FAa2eI6kj1. Does that not suffice? Is there

Hi,
I have a basic question on HDFS. I was reading that HDFS doesnt work well with
low latency data access. Rather it is designed for the high throughput
