  1. Hadoop Online Training Presented By BEST IT Online Training Solutions For Free Demo : 9581241598

  2. Agenda • Big Data • Hadoop design principles • What is Hadoop • MAP Reduce • Hbase • PIG • HIVE For Free Demo : 9581241598

  3. Big Data • Extremely large datasets that are hard to deal with using Relational Databases • Storage/Cost • Search/Performance • Analytics and Visualization • Need for parallel processing on hundreds of machines • ETL cannot complete within a reasonable time • Beyond 24hrs – never catch up For Free Demo : 9581241598

  4. Hadoop design principles • System shall manage and heal itself • Automatically and transparently route around failure • Speculatively execute redundant tasks if certain nodes are detected to be slow • Performance shall scale linearly • Proportional change in capacity with resource change • Compute should move to data • Lower latency, lower bandwidth • Simple core, modular and extensible For Free Demo : 9581241598

  5. What is Hadoop ? • A scalable fault-tolerant grid operating system for data storage and processing • Commodity hardware • HDFS: Fault-tolerant high-bandwidth clustered storage • MapReduce: Distributed data processing • Works with structured and unstructured data • Open source, Apache license • Master (named-node) – Slave architecture For Free Demo : 9581241598

  6. Map Reduce map (in_key, in_value) -> list(out_key, intermediate_value) reduce (out_key, list(intermediate_value)) -> list(out_value) For Free Demo : 9581241598

  7. Example: count word occurrences For Free Demo : 9581241598

  8. HBase • “Project's goal is the hosting of very large tables - billions of rows X millions of columns - atop clusters of commodity hardware” • Hadoop database, open-source version of Google BigTable • Column-oriented • Random access, realtime read/write • “Random access performance on par with open source relational databases such as MySQL” For Free Demo : 9581241598

  9. PIG • High level language (Pig Latin) for expressing data analysis programs • Compiled into a series of MapReduce jobs • Easier to program • Optimization opportunities • grunt> A = LOAD 'student' USING PigStorage() AS (name:chararray, age:int, gpa:float);grunt> B = FOREACH A GENERATE name; For Free Demo : 9581241598

  10. HIVE • Managing and querying structured data • MapReduce for execution • SQL like syntax • Extensible with types, functions, scripts • Metadata stored in a RDBMS (MySQL) • Joins, Group By, Nesting • Optimizer for number of MapReduce required • hive> SELECT a.foo FROM invites a WHERE a.ds='<DATE>'; For Free Demo : 9581241598
