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).
Description: Rattlesnakes are highly specialized, venomous reptiles with large bodies and triangle-shaped heads. They are one of the most iconic groups of North American snakes due to the characteristic ârattleâ found at the tip of the tail. The rattle is composed of a series of interlocking scales, which are added to each time the snake molts. Muscle contractions cause the scales to click together, resulting in the rattle sound.
