Question

我正在尝试安装Apache Hive，我将HIVE_HOME和HADOOP_HOME插入hive_config.sh并将一些hive jar复制到$ HADOOP_HOME / lib中但是当我尝试使用hive命令启动它时，会出现此错误：

Answer 1

你的hadoop应该处于运行状态。解压下载的配置单元并将权限授予该目录。转到hive / conf目录。将hive-env.sh.template文件发送到hive-env.sh，将hive-default.xml.template文件发送到hive-site.xml。打开hive-evn.sh并在hive-env.sh和HADOOP_HOME中设置JAVA_HOME，并设置配置单元路径。

export HIVE_HOME=/usr/local/hive

然后通过

打开蜂巢终端

hive

默认情况下，hive使用Derby数据库，如果在创建表时发出Metastore错误，请转到metastore / metastore_db并删除* .lck文件。

在.bashrc或.bash_profile中添加JAVA_HOME，HADOOP_HOME，HIVE_HOME。

$cd ~
$vi .bashrc

paste following to the end of the file



#Hadoop variables
export JAVA_HOME=/usr/lib/jvm/jdk/
export PATH=$PATH:$JAVA_HOME/bin
export HADOOP_HOME=/usr/local/hadoop
export PATH=$PATH:$HADOOP_INSTALL/bin
export PATH=$PATH:$HADOOP_INSTALL/sbin
export HADOOP_MAPRED_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_HOME=$HADOOP_INSTALL
export HADOOP_HDFS_HOME=$HADOOP_INSTALL
export YARN_HOME=$HADOOP_INSTALL
export HIVE_HOME=/usr/local/hive
export PATH=$PATH:$HIVE_HOME/bin
###end of paste

Answer 2

hive --service metabore＆amp;

此命令将启动Metastore。

Answer 3

无需启动Metastore，因为运行hive cli的服务也会这样做，只需确保从实例化hive Metastore的同一目录执行hive命令

Answer 4

如果您是CDH用户，则应使用正确的参数构建 Zeppelin 。这些参数将解决CDH 5.3.3的问题：

mvn clean install -Pspark-1.4 -Phadoop-2.4 -DskipTests -Dspark.version=1.4.0 -Dhadoop.version=2.5.0-cdh5.3.3 -Dhive.hive.version=0.13.1-cdh5.3.3

Answer 5

要解决上述问题，启动hive Metastore服务对我有用

   $ hive --service metastore

Answer 6

从属性中，它将仅创建数据库，但不创建模式。尝试在MySQL中创建Hive Metastore所需的模式

cd $ HIVE_HOME / scripts / metastore / upgrade / mysql / ＆LT;使用命令登录mysql（mysql -u root -p）其中root是用户名，密码将被询问＆gt;

mysql> use metastore;
 mysql> source hive-schema-<your_version>.mysql.sql;

例如source hive-schema-2.1.0.mysql.sql; 然后使用以下命令重启hive Metastore进程：
