我正在尝试在 Ubuntu 14.0.4 上配置 Hive 1.2.1。
我已经设置了环境变量并创建了 hive-site.xml 和 hive-config.sh。我已经安装了 MYSQL 和 MySQL 连接器并将其放在 hive/lib 文件夹中。我已在 hive-confing.sh 中更新了 HIVE_HOME 和 PATH 以及 HADOOP_HOME 的环境变量。
hive-site.xml:
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost/metastore_db?createDatabaseIfNotExist=true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>huser</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>huser</value>
</property>
<property>
<name>datanucleus.autoCreateSchema</name>
<value>false</value>
</property>
<property>
<name>datanucleus.fixedDatastore</name>
<value>true</value>
</property>
每当我尝试点击 $hive 命令时，我都会收到以下异常:

最佳答案
首先检查 mysql 用户名和密码与 hive-site.xml 文件是否匹配，
您尚未设置hdfs的仓库目录路径，请将此属性添加到hive-site.xml。
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/work/warehouse</value>
</property>
编辑连接 url 值和端口号，如下所示
<name>javax.job.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive-db?createDatabaseIfNotExist=true</value>
</property>
立即尝试。
