環境

hadoop3.1.2

centOS 7

mysql 5.1.32

安裝

• 下載並解壓到/home/hadoop，避免沒有許可權建立metastore_db檔案

• 配置hive環境變數

• 修改配置檔案 進入hive/conf

mv hive-default.xml.template hive-default.xml 
vi hive-site.xml 

hive-site.xml內容如下

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
    <description>JDBC connect string for a JDBC metastore</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionDriverName</name>
    <value>com.mysql.jdbc.Driver</value>
    <description>Driver class name for a JDBC metastore</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionUserName</name>
    <value>hive</value>
    <description>username to use against metastore database</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value>hive</value>
    <description>password to use against metastore database</description>
  </property>
</configuration>

 

mysql的地址localhost根據具體安裝ip修改

• 配置mysql環境 進入mysql終端，執行以下命令

create database hive; 
grant all on *.* to hive@localhost identified by 'hive';
flush privileges; 

在hive的lib檔案下加入mysql-connector-java-5.1.32.jar驅動，否則啟動hive會提示找不到驅動

• 初始化當前 Hive 版本的 Metastore 架構

schematool -dbType mysql -initSchema 

問題

• java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveM
