集成hive 的前提是apache hadoop 集群能够正常启动。
hadoop 版本 apach2.6.0 hive 版本：1.2.1
1、安装mysql 并赋予权限：
1.1：创建hive 用户和密码：
Create user ‘hive’ identified by ‘123456’
1.2：创建数据库：create database hive DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
1.3：授权允许远程登陆：grant all privileges on *.* to ‘user‘@‘hostname‘ identified by ‘passwd‘ with grant option;
flush privileges;
1.4 将mysql 驱动复制到 hive/lib 目录下
mysql-connector-java-5.1.38-bin.jar
2、hive 配置文件在conf 目录下：hive-env.sh
cp hive-env.sh.template hive-env.sh
最后添加如下配置：
export JAVA_HOME=/usr/java/jdk1.7.0_79 export HIVE_HOME=/home/hadoop/hive-1.2.1-bin export HADOOP_HOME=/home/hadoop/hadoop-2.6.0
3、hive-site.xml
3.1hdfs 上的文件需要事先创建，如果出现权限问题修改对应的权限即可：hadoop dfs -chmod -R 777 hdfs://node17:9000/hive/scratchdir
3.2需要将下述jar文件复制到hive/lib目录下
home/hadoop/hive-1.2.1-bin/lib/hive-hbase-handler-1.2.1.jar
file:///home/hadoop/hive-1.2.1-bin/lib/protobuf-java-2.5.0.jar,
file:///home/hadoop/hive-1.2.1-bin/lib/hbase-client-1.0.0.jar,
file:///home/hadoop/hive-1.2.1-bin/lib/hbase-common-1.0.0.jar,
file:///home/hadoop/hive-1.2.1-bin/lib/zookeeper-3.4.6.jar,
file:///home/hadoop/hive-1.2.1-bin/lib/guava-12.0.1.jar

出现问题：

解决办法：
启动metastore service服务即可。
./hive --service metastore
解决办法：
删除 yarn 下的 jline-0.9.94.jar jar 包即可。
./hadoop-2.6.0/share/hadoop/yarn/lib/jline-0.9.94.jar
