"I once found myself trying to debug a job that took a full six hours to fail. It took more than a week -- a whole week! -- to find and fix the problem. Of course, I was doing other things at the same time, but the need to constantly check up on the status of the job was a huge drain on my energy and productivity. It was a Very Bad Week." — Abe Gong, Hadoop Developer
ScaleOut hServer™ enables you to develop your code rapidly with results in seconds — before it goes into batch. What's more, ScaleOut hServer comes in a free community edition for use on up to 4 servers or 256GB of data, indefinitely.
