Abstract

This is the official document for Apache HBase, HBase is a distributed, versioned (versioned), built in a column database on Apache Hadoop and Apache zookeeper.

I am (translator) familiar with HBase source code, engaged in the development of hbase work, if there is no clear, welcome to discuss. Mailbox yankaycom@gmail.com
