What is Hadoop? The Hadoop framework encompasses a large number of open source software components with a set of core modules for capturing, processing, managing and analyzing massive volumes of data that's surrounded by a variety of supporting technologies. The core components include:
The Catskill Mountains have two poisonous snakes. The Timber Rattlesnake (Crotalus horridus) and the Northern Copperhead (Agkistrodon contortrix mokasen). 1  Timber Rattlesnake - Overlook Mountain (from the Overlook Mountain House to the fire tower).  Timber Rattlesnake - Echo Lake (near Overlook Mountain).
Rattlesnakes are usually identified by their warning rattle â a hiss or buzz â made by the rattles at the tip of their tails. A rattlesnake is born with a button, or rattler, and acquires a new rattle section each time it molts.
