Thanks to everyone for all responses. I would like to comment few things. I am working on Apache Hadoop from quite few years now. This forum has always resolved my queries upfront.
@Todd: +1 for your response. It clears out my query. @Arun C Murthy: Thanks for your response. I always asked relevant questions on this forum. If I have query regarding the Hadoop functionality then I think this is the best place where I can get hints to proceed in my way. Through my query I was not targeting any vendors like MapR, CDH or Hortonworks but just like a normal user of Apache Hadoop I wanted to clear out a simple question. I hope this clears out my intention of putting this question here.
