(BDT309) Data Science & Best Practices for Apache Spark on Amazon EMRAmazon Web Services
Organizations need to perform increasingly complex analysis on their data — streaming analytics, ad-hoc querying and predictive analytics — in order to get better customer insights and actionable business intelligence. However, the growing data volume, speed, and complexity of diverse data formats make current tools inadequate or difficult to use. Apache Spark has recently emerged as the framework of choice to address these challenges. Spark is a general-purpose processing framework that follows a DAG model and also provides high-level APIs, making it more flexible and easier to use than MapReduce. Thanks to its use of in-memory datasets (RDDs), embedded libraries, fault-tolerance, and support for a variety of programming languages, Apache Spark enables developers to implement and scale far more complex big data use cases, including real-time data processing, interactive querying, graph computations and predictive analytics. In this session, we present a technical deep dive on Spark running on Amazon EMR. You learn why Spark is great for ad-hoc interactive analysis and real-time stream processing, how to deploy and tune scalable clusters running Spark on Amazon EMR, how to use EMRFS with Spark to query data directly in Amazon S3, and best practices and patterns for Spark on Amazon EMR.

Combined supervised and unsupervised neural networks for pulse shape discrimi...Samuel Jackson
Our methodology for pulse shape discrimination is split into two steps. Firstly, we learn a model to discriminate between pulses using "clean" low-rate examples by removing pile-up & saturated events. In addition to traditional tail sum discrimination, we investigate three different choices for discrimination between γ-pulses, fast, thermal neutrons. We consider clustering the pulses directly using Gaussian Mixture Modelling (GMM), using variational autoencoders to learn a representation of the pulses and then clustering the learned representation (VAE+GMM) and using density ratio estimation to discriminate between a mixed (γ + neutron) and pure (γ only) sources using a multi-layer perceptron (MLP) as a supervised learning problem.
Secondly, we aim to classify and recover pile-up events in the < 150 ns regime by training a single unified multi-label MLP. To frame the problem as a multi-label supervised learning method, we first simulate pile-up events with known components. Then, using the simulated data and combining it with single event data, we train a final multi-label MLP to output a binary code indicating both how many and which type of events are present within an event window.

DESIGN AND DEVELOPMENT OF AUTO OXYGEN CONCENTRATOR WITH SOS ALERT FOR HIKING ...JeevanKp7
Long-term oxygen therapy (LTOT) and novel techniques of evaluating treatment efficacy have enhanced the quality of life and decreased healthcare expenses for COPD patients.
The cost of a pulmonary blood gas test is comparable to the cost of two days of oxygen therapy and the cost of a hospital stay is equivalent to the cost of one month of oxygen therapy, long-term oxygen therapy (LTOT) is a cost-effective technique of treating this disease.
A small number of clinical investigations on LTOT have shown that it improves the quality of life of COPD patients by reducing the loss of their respiratory capacity. A study of 8487 Danish patients found that LTOT for 1524 hours per day extended life expectancy from 1.07 to 1.40 years.

5. What is EMR?
5
Elastic MapReduce
Managed Hadoop framework on EC2 instances.
Includes Spark, HBase, Presto, Hive & more
Several integration points with AWS.
6. Basic blocks of
EMR
• Master node:
The master node manages the cluster
and typically runs master components
of distributed applications.
All the major services like spark-
history server, resource manager, and
node manager runs on the master
node.
6
7. Basic blocks of
EMR
• Core node:
A node with software components
that run tasks and store data in the
Hadoop Distributed File System (HDFS)
on your cluster.
Multi-node clusters have at least one
core node.
7
8. Basic blocks of
EMR
• Task node:
A node with software components
that only runs tasks, and you can use
task nodes to add power to perform
parallel computation tasks on data,
such as Hadoop MapReduce tasks and
Spark executors.
Task nodes don’t run the Data Node
daemon nor store data in HDFS.
8
9. Launch types of
EMR
• EMR on EKS cluster.
• EMR serverless (November 2021.)
• EMR on EC2 instances.
• Instance Group
• Instance Fleets
9
10. EMR Storage
HDFS
• Hadoop Distributed File System
• Multiple copies stored across cluster instances
for redundancy
• Files stored as blocks (128MB default size)
• Ephemeral – HDFS data is lost when cluster is
terminated!
• But, useful for caching intermediate results or
workloads with significant random I/O
• Hadoop tries to process data where it is stored
on HDFS
Local file system:
• Suitable only for temporary data (buffers,
caches, etc)
10
EMRFS:
• Access S3 as if it were HDFS
• Allows persistent storage after cluster
termination
• EMRFS Consistent View – Optional for S3
consistency
• Uses DynamoDB to track consistency
• May need to tinker with read/write
capacity on DynamoDB
• New in 2021: S3 is Now Strongly
Consistent!
11. EMR Scaling
EMR Automatic Scaling :
• The old way of doing it
• Custom scaling rules based on CloudWatch
metrics
• Supports instance groups only.
EMR Managed Scaling:
• Support instance groups and instance fleets
• Scales spot, on-demand, and instances in a
Savings Plan within the same cluster
• Available for Spark, Hive, and YARN workloads
11
Scale-up Strategy
• First, add core nodes, then task nodes,
up to max units specified
Scale-down Strategy
• First removes task nodes, then core
nodes, no further than minimum
constraints
Spot nodes always removed before on-demand
instances
12. EMR
Security
• EMRFS
• S3 encryption (SSE or CSE) at rest
• TLS in transit between EMR nodes and S3
• S3
• SSE-S3, SSE-KMS
• Local disk encryption
• Spark communication between drivers &
executors is encrypted
• Hive communication between Glue Meta store
and EMR uses TLS
• Force HTTPS (TLS) on S3 policies with aws:
Secure Transport.
• IAM roles and policy.
12
13. EMR Pricing
• Amazon EMR on Amazon EC2:
• The Amazon EMR price is added to the Amazon EC2 price (the
price for the underlying servers) and Amazon Elastic Block
Store (Amazon EBS) price (if attaching Amazon EBS volumes).
These are also billed per second, with a one-minute minimum.
• Amazon EMR on Amazon EKS:
• The Amazon EMR price is added to the Amazon EKS pricing or
any other services used with EKS. You can run EKS on AWS
using either EC2 or AWS Fargate.
• Amazon EMR Serverless:
• With EMR Serverless, there are no upfront costs, and you pay
for only the resources you use. You pay for vCPU, memory, and
storage resources consumed by your applications.
13
20. Spark Memory Allocation
• Storage Memory:
• It’s mainly used to store Spark cache data, such as RDD cache, Unroll data, and so on.
• Execution Memory:
• It’s mainly used to store temporary data in the calculation process of Shuffle, Join,
Sort, Aggregation, etc.
• User Memory:
• It’s mainly used to store the data needed for RDD conversion operations, such as the
information for RDD dependency.
• Reserved Memory:
• The memory is reserved for the system and is used to store Spark’s internal object
20
21. EMR Bootstrap
• Use a bootstrap action to install additional
software or customize the configuration of
cluster instances
• Bootstrap actions are scripts that run on
the cluster after Amazon EMR launches
the instance using the Amazon Linux
Amazon Machine Image (AMI).
• Bootstrap actions run before Amazon EMR
installs the applications that you specify
when you create the cluster and before
cluster nodes begin processing data.
