Brief introduction to hadoop and HBase


Hadoop Motivation • HW improvements through the years … – CPU Speeds: 40 MIPS (1990) -> 50 GIPS (2010) => 1,250x – RAM Memory: 640kB (1990) -> 8GB (2010) => 12,500x – Disk Capacity & Cost: 40 MB (1990 for $400) -> 1 TB (2010 for $100) => 25,000x • What about disk read speed / disk latency? – 4.4 MB/s in 1990 – 100 MB/s in 2010 => JUST 25x faster – => parallel read from multiple-disks – it’s not just about reads, but parallel writes as well

Hadoop motivation - issues • Parallel reads and writes brings challenges … – Hardware failure • Disks failure => replication? => RAID? – Data combination • Combining data from disks • Solution … HADOOP – Hadoop Distributed File System (HDFS) – MapReduce programming model – analysis system • Abstracts from disk R/W to computation over sets of keys and values

Hadoop HDFS • Big Virtual File System • Master – Slave architecture


Hadoop X Relational DB Relational DB MapReduce Data size GBs TBs / PBs Access Interactive / Batch Batch Updates Read & Write Write once / multiple reads Structure Static schema Dynamic schema (analyst chooses it) Integrity High Low Scaling Non linear Linear

Hadoop 1 vs Hadoop 2 • Hadoop 1 SPOF NameNode • Security • Hadoop 2 promotes cluster to “universal computational cluster” • Removes bottlenecks in Map-Reduce

HBase features • NoSQL database • Column oriented DB • Google’s BigTable implementation • Linear and modular scalability • Strictly consistent reads and writes. • Automatic and configurable sharding of tables • Automatic failover support between RegionServers. • Convenient base classes for backing Hadoop MapReduce jobs with Apache HBase tables. • Easy to use Java API for client access. • Block cache and Bloom Filters for real-time queries. • Query predicate push down via server side Filters • Thrift gateway and a REST-ful Web service that supports XML, Protobuf, and binary data encoding options
