Online Training CCA 131 – Cloudera Certified Hadoop and Spark Administrator
CCA 131 is certification exam conducted by the leading Big Data Vendor, Cloudera. This online proctored exam is scenario based which means it is very hands on. You will be provided with multi-node cluster and need to take care of given tasks.To prepare the certification one need to have hands on exposure in building and managing the clusters. However, with limited infrastructure it is difficult to practice in a laptop. We understand that problem and built the course using Google Cloud Platform where you can get credit up to $300 till offer last and use it to get hands on exposure in building and managing Big Data Clusters using CDH.Required SkillsInstall – Demonstrate an understanding of the installation process for Cloudera Manager, CDH, and the ecosystem projects.Set up a local CDH repositoryPerform OS-level configuration for Hadoop installationInstall Cloudera Manager server and agentsInstall CDH using Cloudera ManagerAdd a new node to an existing clusterAdd a service using Cloudera ManagerConfigure – Perform basic and advanced configuration needed to effectively administer a Hadoop clusterConfigure a service using Cloudera ManagerCreate an HDFS user’s home directoryConfigure NameNode HAConfigure ResourceManager HAConfigure proxy for Hiveserver2/ImpalaManage – Maintain and modify the cluster to support day-to-day operations in the enterpriseRebalance the clusterSet up alerting for excessive disk fillDefine and install a rack topology scriptInstall new type of I/O compression library in clusterRevise YARN resource assignment based on user feedbackCommission/decommission a nodeSecure – Enable relevant services and configure the cluster to meet goals defined by security policy; demonstrate knowledge of basic security practicesConfigure HDFS ACLsInstall and configure SentryConfigure Hue user authorization and authenticationEnable/configure log and query redactionCreate encrypted zones in HDFSTest – Benchmark the cluster operational metrics, test system configuration for operation and efficiencyExecute file system commands via HTTPFSEfficiently copy data within a cluster/between clustersCreate/restore a snapshot of an HDFS directoryGet/set ACLs for a file or directory structureBenchmark the cluster (I/O, CPU, network)Troubleshoot – Demonstrate ability to find the root cause of a problem, optimize inefficient execution, and resolve resource contention scenariosResolve errors/warnings in Cloudera ManagerResolve performance problems/errors in cluster operationDetermine reason for application failureConfigure the Fair Scheduler to resolve application delaysOur ApproachYou will start with creating Cloudera QuickStart VM (in case you have laptop with 16 GB RAMwith Quad Core). This will facilitate you to get comfortable with Cloudera Manager.You will be able to sign up for GCPand avail credit up to $300 while offer lasts. Credits are valid up to year.You will then understand brief overview about GCPand provision 7 to 8 Virtual Machines using templates. You will also attaching external hard drive to configure for HDFSlater.Once servers are provisioned, you will go ahead and set up Ansible for Server Automation.You will take care of local repository for Cloudera Manager and Cloudera Distribution of Hadoop using Packages.You will then setup Cloudera Manager with custom database and then Cloudera Distribution of Hadoop using Wizard that comes as part of Cloudera Manager.As part of setting up of Cloudera Distribution of Hadoop you will setup HDFS, learn HDFS Commands, Setup YARN, Configure HDFSand YARNHigh Availability, Understand about Schedulers, Setup Spark, Transition to Parcels, Setup Hive and Impala, Setup HBase and Kafka etc.Once all the services are configured, we will revise for exam by mapping with required skills of the exam.

Investing in yourself through Learning
As a society, we spend hundreds of billions of dollars measuring the return on our financial assets. Yet, at the same time, we still haven’t found convincing ways of measuring the return on our investments in developing people.
And I get it: If my bank account pays me 1% a year, I can measure it to the penny. We’ve been collectively trained to expect neat and precise ROI calculations on everything, so when it’s applied to something as seemingly squishy as how effectively people are learning in the workplace, the natural inclination is to throw up our hands and say it can’t be done. But we need to figure this out. In a world where skills beat capital, the winners and losers of the next 30 years will be determined by their ability to attract and develop great talent.
Fortunately, corporate learning & development (L&D), like most business functions, is evolving quickly. We can embrace some level of ambiguity and have rigor when measuring the ROI of learning. It just might look a little different than an M.B.A. would expect to see in an Excel model.
