kudu集成impala - 爱码网

Kudu 与 Apache Impala （孵化）紧密集成，允许开发人员使用 Impala 使用 Impala 的 SQL 语法从 Kudu tablets 插入，查询，更新和删除数据；

安装impala

安装规划

kudu集成impala

1：Imppalla catalog服务将SQL语句做出的元数据变化通知给集群的各个节点

2：Impala Statestore检查集群各个节点上Impala daemon的健康状态

主节点hadoop01执行以下命令进行安装

yum  install  impala -y
yum install impala-server -y
yum install impala-state-store  -y
yum install impala-catalog  -y
yum  install  impala-shell -y

从节点hadoop02与hadoop03安装以下服务

yum install impala-server -y

yum  install  impala -y

所有节点配置impala

修改hive-site.xml

impala依赖于hive，所以首先需要进行hive的配置修改；

Hadoop01机器修改hive-site.xml内容如下

hive-site.xml配置

vim /opt/cdh/hive-1.1.0-cdh5.14.0/conf/hive-site.xml
