  • 4. HBase – Architecture Where does Hbase sit in relation to Hadoop ?
  • 5. HBase – Architecture ● HBase is a data store ● Uses Hadoop for distributed storage ● Data stored across region servers ● Region server data spread across HDFS data nodes ● A write ahead log (WAL) is used to record changes
  • 6. HBase – Storage ● What is the architecture ?
  • 7. HBase – Storage ● Client makes call i.e. put ● Request RPC'ed as key value to Region server ● Key Value routed to region for row ● Data is written to WAL ● Data written to region memStore ● If region server cashes WAL can be used to recover data
  • 8. HBase – Related Projects ● Apache Flume – move large data sets to Hadoop ● Apache Sqoop – cmd line, move rdbms data to Hadoop ● Apache Hbase – Non relational database ● Apache Pig – analyse large data sets ● Apache Oozie – work flow scheduler ● Apache Mahout – machine learning and data mining ● Apache Hue – Hadoop user interface ● Apache Zoo Keeper – configuration / build
