Apache Hive：无法实例化 org.apache.hadoop.hive.metastore.HiveMetaStoreClient

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 但是当我尝试使用hive命令启动它时出现此错误：

请提供任何帮助！

您的 hadoop 应该处于运行状态。解压下载的配置单元并授予目录权限。进入 hive/conf 目录。将 hive-env.sh.template 文件制作为 hive-env.sh，将 hive-default.xml.template 文件制作为 hive-site.xml。打开 hive-evn.sh 并在 hive-env.sh 和 HADOOP_HOME 中设置 JAVA_HOME，并设置 hive 路径。

export HIVE_HOME=/usr/local/hive

然后通过以下方式打开配置单元终端

hive

默认情况下，hive 采用 Derby 数据库，如果在创建表时出现 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
