HBase is an open source, non-relational, distributed database modeled after Google's BigTable and is written in Java. It is developed as part of Apache Software Foundation's Apache Hadoop project and runs on top of HDFS (Hadoop Distributed Filesystem), providing BigTable-like capabilities for Hadoop. That is, it provides a fault-tolerant way of storing large quantities of sparse[clarification needed] data.
HBase features compression, in-memory operation, and Bloom filters on a per-column basis as outlined in the original BigTable paper.[1] Tables in HBase can serve as the input and output for MapReduce jobs run in Hadoop, and may be accessed through the Java API but also through REST, Avro or Thrift gateway APIs.
In the coming step we will setup a HBase on Ubuntu in standalone mode.
Step 1: Download the HBase binaries from any of the fallowing available mirrors using link : http://www.apache.org/dyn/closer.cgi/hbase/
Step 2: Unzipped the content to any of the local directory,preferably home directory.here is the snapshot of the HBase home directory
Step 3:Change EXPORT JAVA_HOME to the location where java is installed and change HBASE_HEAPSIZE to 1000MB(see the image)
Step 4:Change conf/Hbase-Site.Xml as fallows
Step 5: Copy Hadoop-1.0.4.jar to HBase_home_folder/lib folder
Step 6: Copy ${HADOOP_HOME}/lib/commons-configuration-*.jar to ${HBASE_HOME}/lib/
Step 7: Now its done,start the HBase server using fallowing command bin/start-hbase.sh
Step 8: run jps command to know which services are running,you will find the fallowing deamon up and running.
