Hadoop runs well on Linux. The operating systems of choice are: RedHat Enterprise Linux (RHEL): This is a well tested Linux distro that is geared for Enterprise. Comes with RedHat support CentOS: Source compatible distro with RHEL. Free. Very popular for running Hadoop. Use a later version (version 6.x). Ubuntu: The Server edition of Ubuntu is a good fit -- not the Desktop edition. Long Term Support (LTS) releases are recommended, because they continue to be updated for at least 2 years. Java Hadoop is written in Java. The recommended Java version is Oracle JDK 1.6 release and the recommended minimum revision is 31 (v 1.6.31). So what about OpenJDK? At this point the Sun JDK is the 'official' supported JDK. You can still run Hadoop on OpenJDK (it runs reasonably well) but you are on your own for support :-) read less

Hi, What is opinion on Big data analytics for MBA graduates who doesn't know coding. Please suggest. Is it Coding related course.
You should focus on the analytics part of Data Science, and not on big data. Analytics require knowledge of business along with Data Science skills.
