· Rack topology

· Installation

· Multi-tenancy

· Directory structure, logs

· Benchmarking

· Labs: cluster install, run performance benchmarks

 

3: HDFS operations

· Concepts (horizontal scaling, replication, data locality, rack awareness)

· Nodes and daemons (NameNode, Secondary NameNode, HA Standby NameNode, DataNode)

· Health monitoring

· Command-line and browser-based administration

· Adding storage, replacing defective drives

· Labs: getting familiar with HDFS command lines

 

4: Data ingestion

· Flume for logs and other data ingestion into HDFS

· Sqoop for importing from SQL databases to HDFS, as well as exporting back to SQL

· Hadoop data warehousing with Hive

· Copying data between clusters (distcp)

· Using S3 as complementary to HDFS

· Data ingestion best practices and architectures

· Labs: setting up and using Flume, the same for Sqoop

· MapReduce operations and administration

· Parallel computing before mapreduce: compare HPC vs Hadoop administration

· New actors: ResourceManager, NodeManager, Application Master

· Installing YARN

· Job scheduling under YARN

· Labs: investigate job scheduling

· Advanced topics

· Hardware monitoring

· Cluster monitoring

· Adding and removing servers, upgrading Hadoop

· Backup, recovery and business continuity planning

· Oozie job workflows

· Hadoop high availability (HA)

· Hadoop Federation

· Securing your cluster with Kerberos

· Labs: set up monitoring

 

· Optional tracks

· Cloudera Manager for cluster administration, monitoring, and routine tasks; installation, use. In this track, all exercises and labs are performed within the Cloudera distribution environment (CDH5)

· Ambari for cluster administration, monitoring, and routine tasks; installation, use. In this track, all exercises and labs are performed within the Ambari cluster manager and Hortonworks Data Platform (HDP 2.0)
