Why hadoop should be built in JAVA?

For integrity and stability, it is good for hadoop to be implemented in Java

But, when it comes to speed issue, I have a question...

How will it be if HADOOP is implemented in C or Phython?

Bill Graham: There was a fairly long discussion on this topic at the beginning of the year FYI: http://search-hadoop.com/m/JvSQe2wNlY11
Dhruv: Java's features such as garbage collection, run time array index checking, cleaner syntax (no pointers) make it a good language for Hadoop. One can develop MapReduce apps faster and maintain code easier than in case of C/C++, allowing clients to focus on their business logic/use cases. For a fairly high level implementation of MapReduce which uses clusters of COTS hardware as compute nodes, the main bottleneck in most applications will be due to network I/O. In such cases, the speed advantage
Adi: I haven't used anything besides hadoop but in case you are interested in alternate (some of them non-java) M/R frameworks this list is a decent compilation of those https://sites.google.com/site/cloudcomputingsystem/research/programming-model Erlang/Python - http://discoproject.org/ Ruby - http://skynet.rubyforge.org/ -Adi
