![]() Just about every species of snake on earth has teeth, but the Anacondas teeth are not used for chewing. Yellow Anacondas live in mostly aquatic habitats including swamps, marshes and brush covered banks of slow moving rivers and streams. Yellow Anacondas have a yellow/brown base color with black blotches and rosettes. The Yellow Anaconda is smaller than the more well known Green Anaconda and reaches an average adult length of about 3 metres (9.8 feet). The Yellow Anaconda (Eunectes notaeus), is native to South America in countries such as Bolivia, Paraguay, Uruguay, western Brazil and northeast Argentina. Their eyes are set high on their head so as to allow the snake to be able to see out of the water without exposing the rest of its body. Their head is narrow compared to the rest of the body, with most exhibiting distinctive orange-yellow striping on either side. The primary color of the Green Anaconda is an olive green, with black blotches that run the length of the body. It can weigh 250 kilograms (551 pounds) and have a girth of more than 30 centimetres (11.8 inches) in diameter.įemale anacondas are significantly larger than males, having the largest sexual dimorphism of all the snakes. It rivals the Reticulated Python in length, but is typically considerably heavier. The Green Anaconda is among the largest snakes in the world. The Green Anaconda (Eunectes murinus) is the largest member of the boa family of snakes and the most heavy bodied member of the super-order ‘Squamata’. Some Anacondas, which live in the water, can reach up to 30 feet in length. There is some debate about the maximum size of Anacondas and there have been unverified claims of enormous snakes alleged to be as long as 30 – 45 metres (98.4 – 147.6 feet). The Latin name for Anaconda is ‘Eunectes’ meaning ‘good swimmer’. Anacondas as members of the boa family are sometimes called ‘water boas’. Local names for the Anaconda in South America include the Spanish term ‘matatoro’, meaning ‘bull killer’, and the Native American terms ‘sucuri’ and ‘yakumama’. It is likely due to its vague similarity to the large Asian pythons. It is unclear how the name originated so far from the snakes native habitat. The Yellow Anaconda can be found as far south as Argentina. ![]() In his spare time, he likes to play music, learn, develop tools and write documentation to further help others – both colleagues and customers alike.Anacondas are four species of aquatic boa inhabiting the swamps and rivers of the dense forests of tropical South America. He works to provide advice and solutions to our customers on their Big Data projects and workflows on AWS. John Ohle is an AWS BigData Cloud Support Engineer II for the BigData team in Dublin. Learn how to use Apache Oozie workflows to automate Apache Spark jobs on Amazon EMR. If you have questions or suggestions, please leave a comment below. Now when your Python job runs in Oozie, any imported packages that are implicitly imported by your Pyspark script are imported into your job within Oozie directly from the Anaconda platform. If you tried to run this using standard Python, you’d encounter the following error: The myPysparkProgram.py has successfully imported the numpy library from the Anaconda platform and has produced some output with it. To test this out, you can use the following job.properties and myPysparkProgram.py file, along with the following steps: archives hdfs:///tmp/myLocation/anaconda.zip#anaconda_remoteĪction failed, error message conf _PYTHON=./anaconda_remote/bin/python executor-memory 2G -num-executors 2 -executor-cores 2 -driver-memory 3g Hdfs:///user/oozie/apps/myPysparkProgram.py It is shown here separated for readability purposes only. This command must be typed as one line, as shown below. To create a three-node cluster in the us-east-1 region, issue an AWS CLI command such as the following. Use the latest release, and include Apache Hadoop, Apache Spark, Apache Hive, and Oozie. Spin up an Amazon EMR cluster using the console or the AWS CLI. Walkthroughįor this post, you walk through the following tasks: I describe how to run jobs using a popular open source scheduler like Oozie. This post focuses on setting up an Anaconda platform on EMR, with an intent to use its packages with Oozie. One such popular platform that contains these types of packages (and more) is Anaconda. However, Oozie can be difficult to configure when you are trying to use popular Python packages (such as “pandas,” “numpy,” and “statsmodels”), which are not included by default. ![]() Amazon EMR allows data scientists to spin up complex cluster configurations easily, and to be up and running with complex queries in a matter of minutes.ĭata scientists often use scheduling applications such as Oozie to run jobs overnight. In the world of data science, users must often sacrifice cluster set-up time to allow for complex usability scenarios.
