Hi All,
I was setup a single node hadoop (hadoop-0.20.0) and is able to
run that have only Map Tasks, but If a task have Map & Reduce tasks, then
MapTask is thorwing exceptions saying "Too many fetch failures" and the
reduceTask is not starting at all. can some one please guide whats the
Google app engine has the model whereby all computation is done in the
context of a HTTP request, with fairly hard limits on CPU, memory and
thread resources. There is no way to create a 'daemon', or long
running thread. That would defeat the horizontal scalability benefits
of a system like GAE.
Hi,
You can run any Java app server you like on EC2, such as Tomcat or
Resin, and also take advantage of the AWS MapReduce framework.
HTH,
Fred
