Abstract

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

I (translator) familiar with the source code of HBase, engaged in hbase development operations, if there is not clear, welcome to discuss together. Email yankaycom@gmail.com
