18. 18Pivotal Confidential–Internal Use Only Hadoop YARN Ÿ  Cluster resource manager Ÿ  Manages CPU and RAM allocation Ÿ  Schedulers are pluggable Ÿ  Can handle different resource pools Ÿ  Supports both MR and non-MR workload

19. 19Pivotal Confidential–Internal Use Only Hadoop YARN

20. 20Pivotal Confidential–Internal Use Only Hadoop MapReduce Ÿ  Framework for distributed data processing Ÿ  Two main operations: map and reduce Ÿ  Data hits disk after “map” and before “reduce” Ÿ  Scales to thousands of servers Ÿ  Can process petabytes of data Ÿ  Extremely reliable

21. 21Pivotal Confidential–Internal Use Only Hadoop MapReduce

22. 22Pivotal Confidential–Internal Use Only Hadoop HBase Ÿ  Distributed key-value store Ÿ  Data is sharded by key Ÿ  Data is stored in sorted order Ÿ  Stores multiple versions of the row Ÿ  Easily scales

23. 23Pivotal Confidential–Internal Use Only Hadoop HBase

24. 24Pivotal Confidential–Internal Use Only Hadoop Hive Ÿ  Query engine with SQL-like syntax Ÿ  Translates HiveQL query to MR / Tez / Spark job Ÿ  Processes HDFS data Ÿ  Supports UDFs and UDAFs

25. 25Pivotal Confidential–Internal Use Only Hadoop Hive

26. 26Pivotal Confidential–Internal Use Only Hadoop Works well for Ÿ  Write Once Read Many Ÿ  100+ server clusters Ÿ  Both relational and non-relational data Ÿ  High concurrency Ÿ  Batch processing and analytical workload Ÿ  Elastic scalability

27. 27Pivotal Confidential–Internal Use Only Hadoop Not the best choice for Ÿ  Write-heavy workloads Ÿ  Small clusters Ÿ  Analytical DWH cases Ÿ  OLTP and event stream processing Ÿ  Cost savings
