Apache Hbase Download
Now we are all set to run HBase, to start HBase execute the command below from the bin folder. Open Command Prompt and cd to Hbase’ bin directory Run start-hbase.cmd. Apache HBase is a distributed, scalable, non-relational (NoSQL) big data store that runs on top of HDFS. It is an open-source database which provides real-time read/write access to Hadoop data. It is column-oriented and horizontally scalable. HBase can host very large tables such as billions of rows and millions of columns.

HBase is an open-sourcenon-relationaldistributed database modeled after Google'sBigtable and written in Java. It is developed as part of Apache Software Foundation's Apache Hadoop project and runs on top of HDFS (Hadoop Distributed File System) or Alluxio, providing Bigtable-like capabilities for Hadoop. That is, it provides a fault-tolerant way of storing large quantities of sparse data (small amounts of information caught within a large collection of empty or unimportant data, such as finding the 50 largest items in a group of 2 billion records, or finding the non-zero items representing less than 0.1% of a huge collection).
HBase features compression, in-memory operation, and Bloom filters on a per-column basis as outlined in the original Bigtable paper.[2] 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. HBase is a column-oriented key-value data store and has been widely adopted because of its lineage with Hadoop and HDFS. HBase runs on top of HDFS and is well-suited for faster read and write operations on large datasets with high throughput and low input/output latency.
HBase is not a direct replacement for a classic SQLdatabase, however Apache Phoenix project provides a SQL layer for HBase as well as JDBC driver that can be integrated with various analytics and business intelligence applications. The Apache Trafodion project provides a SQL query engine with ODBC and JDBC drivers and distributed ACID transaction protection across multiple statements, tables and rows that use HBase as a storage engine.
