Apache Hive：無法實例化org.apache.hadoop.hive.metastore.HiveMetaStoreClient

Question

我想安裝Apache Hive，我將HIVE_HOME和HADOOP_HOME插入到hive_config.sh中，並將一些Hive jar複製到$ HADOOP_HOME/lib中 但是當吃午飯吧，用hive command這個錯誤出現：

任何幫助請！

你的hadoop應該處於運行狀態。 解壓下載的配置單元並將權限授予目錄。轉到hive/conf目錄。將hive-env.sh.template文件設置爲hive-env.sh和hive-default.xml.template文件到hive-site.xml。打開hive-evn.sh並在hive-env.sh和HADOOP_HOME中設置JAVA_HOME，並設置配置單元路徑。

export HIVE_HOME=/usr/local/hive 

然後打開蜂箱終端通過

hive 

默認蜂巢需要Derby數據庫，如果在創建表時提供​​了metastore的錯誤，去metastore/metastore_db和刪除* .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

如果你是一個CDH用戶，你應該建立齊柏林用正確的參數。這些參數會解決這個問題的CDH 5.3.3：

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 3

要解決上述錯誤時拋出，從蜂巢metastore服務工作對我來說

$ hive --service metastore 

Cloudera的參考文檔上啓動metastore服務：

http://www.cloudera.com/documentation/archive/cdh/4-x/4-7-1/CDH4-Installation-Guide/cdh4ig_topic_18_6.html

Answer 4

hive --service metastore &

該命令將啓動Metastore。

Answer 5

無需啓動metastore作爲服務運行蜂巢CLI會做同樣的只是確保你從你實例蜂巢metastore

Answer 6

從屬性相同的目錄執行蜂巢命令，它會創建唯一的數據庫，但不是架構。嘗試創建MySQL中的蜂巢metastore所需的架構

CD $ HIVE_HOME /腳本/ metastore /使用命令（MySQL的ü根 - P），其中根是升級的用戶名/ MySQL的/ <登錄到MySQL和密碼將被詢問>

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

例如，源hive-schema-2.1.0.mysql.sql; 然後重新啓動蜂房Metastore過程使用：

（配置單元 - 服務Metastore） 希望這將解決問題！
