Hadoop and other applications you install on your Amazon EMR cluster, publish user interfaces as web sites hosted on the master node.
For security reasons, when using EMR-Managed Security Groups, these web sites are only available on the master node's local web server, so you need to connect to the master node to view them. Hadoop also publishes user interfaces as web sites hosted on the core and task nodes. These web sites are also only available on local web servers on the nodes. It is possible to configure a custom security group to allow inbound access to these web interfaces.
Keep in mind that any port on which you allow inbound traffic represents a potential security vulnerability. Carefully review custom security groups to ensure that you minimize vulnerabilities. The following table lists web interfaces that you can view on cluster instances.
These Hadoop interfaces are available on all clusters. For core and task instance interfaces, replace coretask-public-dns-name with the Public DNS name listed for the instance. To find an instance's Public DNS namein the EMR console, choose your cluster from the list, choose the Hardware tab, choose the ID of the instance group that contains the instance you want to connect to, and then note the Public DNS name listed for the instance.
To access web interfaces, you must edit the security groups associated with master and core instances so that they have an inbound rule that allows SSH traffic port 22 from trusted clients, such as your computer's IP address.
Because there are several application-specific interfaces available on the master node that are not available on the core and task nodes, the instructions in this document are specific to the Amazon EMR master node. Accessing the web interfaces on the core and task nodes can be done in the same manner as you would access the web interfaces on the master node.
There are several ways you can access the web interfaces on the master node. The easiest and quickest method is to use SSH to connect to the master node and use the text-based browser, Lynx, to view the web sites in your SSH client.The Apache Ambari project is aimed at making Hadoop management simpler by developing software for provisioning, managing, and monitoring Apache Hadoop clusters.

Ambari Overview What's New? Introduction The Apache Ambari project is aimed at making Hadoop management simpler by developing software for provisioning, managing, and monitoring Apache Hadoop clusters. Ambari enables System Administrators to: Provision a Hadoop Cluster Ambari provides a step-by-step wizard for installing Hadoop services across any number of hosts.
Ambari handles configuration of Hadoop services for the cluster. Manage a Hadoop Cluster Ambari provides central management for starting, stopping, and reconfiguring Hadoop services across the entire cluster. Monitor a Hadoop Cluster Ambari provides a dashboard for monitoring health and status of the Hadoop cluster. Ambari leverages Ambari Metrics System for metrics collection. Ambari leverages Ambari Alert Framework for system alerting and will notify you when your attention is needed e.
Getting Started with Ambari Follow the installation guide for Ambari 2. Get Involved Visit the Ambari Wiki for design documents, roadmap, development guidelines, etc. What's New? Check out the work going on for the upcoming releases.Previously Ambari was only available through a plugin to Ambari View Framework.
Now, it is available to be used on HDInsight, allowing for the deployment and management of Linux clusters. Two of the predefined views in Ambari are Pig and Hive views. Both can be launched through the Ambari portal. Hive view allows one to browse databases, write an execute Hive query, look at job history, set Hive query execution parameters and debug Hive queries.
An Ambari Views link and tab have been added to the portal to simplify the finding of this option. In addition, this portal will permit both Hive and Pig queries, changing of settings, provide a visual explanation of queries, allow the addition of UDFs, and allow monitoring and debugging of Tez jobs.

For this platform to function as developers need and users desire, the developer must be able to:. This enhanced functionality would allow developers to address issues that commonly occur when fetching images, fonts, and payloads.
In self-decoding, the string decoder function must be detected and recorded at every instance and the arguments to those instances must also be recorded.
Ideally, this process would occur semi-automatically. These functions use Vivisect and provide memory, register manipulation, perform stack operations, debugger execution, and breakpoints and function calling.
Once all strings are decoded, the utils script can be used to create IDA Python scripts that creates the comments in the IDB and the script can be fully debugged. Amazon EMR 4. A route to the S3 buckets must also be established to initialize the clusters.
Finally, local filesystems on each node can be used on each slave instance. Other existing security features can also be used.You must be logged in to answer a question.Sunbury asylum
Also, you can access other services such as spark history server, resource manager etc for monitoring jobs and managing resource. Nothing that I found so far that can compare with Ambari or Cloudera Manager for cluster management. Answer this Question You must be logged in to answer a question. Answer Question.

But, aside from cost, other things to look for include ease of operation, controlling, managing, performance, features etc. Straight math: Amazon EMR is a clear winner here. Amazon EMR, the storage option, is limited to S3. Hadoop Performance is directly associated to the number of disk spindles and it can be increased by increasing the number of disks.
HDFS is cost efficient for frequent interactive transactions workload because S3 charges customers based on the number of requests. It is not cost efficient for frequent interactive workloads or near real time big data analysis. Once the job is over, it will be uploaded back to S3 using a multipart upload. Remember the data in an instance store persists only during the lifetime of its associated instance. HVM are capable of using a low latency 10 Gbps network.
Commercial Hadoop distributors like Cloudera, provide simple installation, configuration and add-on services, e. It also comes with Cloudera Manager. It is one of the key differentiators in the market. It manages clusters, software patches across all cluster etc. EC2 Hadoop instances give a little more flexibility in terms of tuning and controlling, according to the need. It makes operations easy and transparent, but it comes with a cost.
EMR is simple and managed by Amazon. Thanks for sharing this- good stuff! Keep up the great work, we look forward to reading more from you in the future! This site uses Akismet to reduce spam.

It also helps you in deciding the relevant service for your organization. Below calculations is for US East region and you can look at details here. We have taken the worst case scenario in which we need to run the big data sets processing throughout the year.
In the case of EMR, we can have one master node and five slaves nodes. In the case of Cloudera, we would need 6 EC2 instances to run 6 nodes. We can reduce the costing by buying reserved the instances but in most of the scenarios you need these clusters for a smaller duration.

This cluster can be terminated after successful completion of the jobs. If your application already running on ec2 then it shall take the resources unnecessarily.
Cloudera uses Apache libraries s3a to access data on S3. Highly Availablity EMR Service monitors the slave nodes and replaces any unhealthy node with a new node. Unlike EMR, Cloudera does not categorize slave nodes into core and task nodes. So you can quickly start a new Hadoop cluster quickly and start processing the data.
2 Choices for Big Data Analysis on AWS: Amazon EMR or Hadoop on EC2
Cloudera is comparatively more difficult to learn and configure. Cloudera Manager has an easy to use web GUI. This helps manage and monitor Hadoop services, cluster, and physical host hardware. This makes it difficult to manage and track various Hadoop services on a running cluster. It provides an administration experience for central IT to reduce costs and deliver agility.
