Explanation: In February, IBM along with other big data industry leaders announced a new initiative called Open Data Platform (ODP) to advance the collaboration and
innovation of big data technologies. ... IBM was one of the founding partners of ODP and has helped pave the way to enable any company to join the Open Data Platform.
ODPi is a nonprofit organization committed to simplification and standardization of the big data ecosystem with common reference specifications and test suites.
Apache Hadoop, its components, and Apache Hadoop Distros, are innovating very quickly and in different ways. This diversity, while healthy in many ways, also slows the Big Data
Ecosystem. By providing specifications for common Apache Hadoop runtime and operations, reference implementations and test suites, ODPi removes cost and complexity and accelerates
the development of Big Data solutions.

A. Reinforces the role of the Apache Software Foundation (ASF) in the development and governance of upstream projects.
B. Accelerates the delivery of Big Data solutions by providing a well-defined core platform to target.
C. Defines, integrates, tests, and certifies a standard ODPi Coreof compatible versions of select Big Data open source projects.
D. Produces a set of tools and methods that enable members to create and test differentiated offerings based on the ODPi Core.
E. Contributes to ASF projects in accordance with ASF processes and Intellectual Property guidelines.

Correct Answer : Get Lastest Questions and Answer :
Explanation: The RMs have an option to embed the Zookeeper-based ActiveStandbyElector to decide which RM should be the Active. When the Active goes down or becomes
unresponsive, another RM is automatically elected to be the Active which then takes over. Note that, there is no need to run a separate ZKFC daemon as is the case for HDFS because
ActiveStandbyElector embedded in RMs acts as a failure detector and a leader elector instead of a separate ZKFC daemon.
