###2.2.2 官网阅读

环境要求：

Requirements

• Java 1.7 Note: Hive versions 1.2 onward require Java 1.7 or newer. Hive versions 0.14 to 1.1 work with Java 1.6 as well. Users are strongly advised to start moving to Java 1.8 (see HIVE-8607).
• Hadoop 2.x (preferred), 1.x (not supported by Hive 2.0.0 onward). Hive versions up to 0.13 also supported Hadoop 0.20.x, 0.23.x.
• Hive is commonly used in production Linux and Windows environment. Mac is a commonly used development environment. The instructions in this document are applicable to Linux and Mac. Using it on Windows would require slightly different steps.

Installing Hive from a Stable Release (从稳定版本安装hive）

Start by downloading the most recent stable release of Hive from one of the Apache download mirrors (see Hive Releases).

Next you need to unpack the tarball. This will result in the creation of a subdirectory named hive-x.y.z (where x.y.z is the release number):

xxxxxxxxxx
  $ tar -xzvf hive-x.y.z.tar.gz

Set the environment variable HIVE_HOME to point to the installation directory:

xxxxxxxxxx
  $ cd hive-x.y.z
  $ export HIVE_HOME={{pwd}}

Finally, add $HIVE_HOME/bin to your PATH:

xxxxxxxxxx
  $ export PATH=$HIVE_HOME/bin:$PATH

Building Hive from Source（源码安装 了解）

The Hive GIT repository for the most recent Hive code is located here: git clone https://git-wip-us.apache.org/repos/asf/hive.git (the master branch).

All release versions are in branches named "branch-0.#" or "branch-1.#" or the upcoming "branch-2.#", with the exception of release 0.8.1 which is in "branch-0.8-r2". Any branches with other names are feature branches for works-in-progress. See Understanding Hive Branches for details.

默认情况下Metadata(元数据存储)在嵌入式Derby数据库中，其磁盘存储位置由名为javax.jdo.option.Connectionurl的hive配置变量决定。默认情况下，此位置为./metastore_db（参见conf/hive-default.xml）。在嵌入式模式下使用Derby最多一次允许一个用户。若要将Derby配置为在服务器模式下运行，请参见服务器模式下使用Derby的Hive。若要为Hive元存储配置除Derby以外的数据库，请参见Hive Metastore Administration。

需要用到mysql，所以我们先安装mysql。
