配置單元在安裝時不起作用

Question

執行任何命令時，在Hive中出現以下錯誤。

hive> show tables; 
FAILED: Error in metadata: javax.jdo.JDOFatalInternalException: Unexpected exception caught. 
NestedThrowables: 
java.lang.reflect.InvocationTargetException 
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask 

這是在hive.log中。

很明顯與元數據庫的問題，但這個錯誤是相當遲鈍和安裝指南不說有關配置的元數據庫什麼。

Answer 1

我找到了答案在這裏：

：

奇怪的是「希裏什雷迪。刪除$ HADOOP_HOME /構建和每一件事應該罰款答覆從鄭複製」，刪除$ HADOOP_HOME /建設問題走了之後。

Answer 2

我遇到了同樣的問題。
的解決方案是下載這個文件：https://www.mysql.com/downloads/connector/j/，將它解壓縮，從內複製罐子位置：/usr/lib/hive/lib（可能是你的情況不同 - 這是蜂巢庫的位置）
