51 Cloudera s Version of the Stack Data Integration Languages Compilers Data Store Coordination
52 Lecture #5 Hadoop Ecosystem Major Components
53
54 Apache Sqoop Tool designed for efficiently transferring bulk data between Apache Hadoop and structured datastores such as relational databases
55
56 HBASE Column-oriented database management system Key-value store Based on Google Big Table Can hold extremely large data Dynamic data model Not a Relational DBMS
57
58 PIG High level programming on top of Hadoop MapReduce
59 PIG The language: Pig Latin
60 PIG Data analysis problems as data flows
61 PIG Originally developed at Yahoo 2006
62 Pig for ETL
63 Pig for ETL
64 Pig for ETL
65
66 Apache Hive Data warehouse software facilitates querying and managing large datasets residing in distributed storage
67 Apache Hive SQL-like language!
68 Apache Hive Facilitates querying and managing large datasets in HDFS
69 Apache Hive Mechanism to project structure onto this data and query the data using a SQLlike language called HiveQL
70
71 Oozie Workflow scheduler system to manage Apache Hadoop jobs
72 Oozie Oozie Coordinator jobs!
73 Oozie Supports MapReduce, Pig, Apache Hive, and Sqoop, etc.
74
75 Zookeeper Provides operational services for a Hadoop cluster group services
76 Zookeeper Centralized service for: maintaining configuration information naming services providing distributed synchronization and providing group services
77 Zookeeper Centralized service for: maintaining configuration information
78 Zookeeper Centralized service for: maintaining configuration information naming services
79 Zookeeper Centralized service for: maintaining configuration information naming services providing distributed synchronization and providing group services
80 Flume Distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of log data
81 Additional Cloudera Hadoop Components Impala
82
83 Impala Cloudera's open source massively parallel processing (MPP) SQL query engine Apache Hadoop
84 Additional Cloudera Hadoop Components Spark The New Paradigm
85
86 Spark Apache Spark is a fast and general engine for large-scale data processing
87 Spark Benefits Multi-stage in-memory primitives provides performance up to 100 times faster for certain applications
88 Spark Benefits Allows user programs to load data into a cluster's memory and query it repeatedly Well-suited to machine learning!!!
89 Up Next Tour of the Cloudera s Quick Start VM
