記得前2天用sqoop從mysql導入數據到hive出現的錯誤，后面替換mysql-connector-java-5.1.32-bin.jar包解決問題的

我也用這個新的包試試，并且把mysql-connector-java-5.1.6-bin.jar刪除

[jifeng@jifeng02 mysql-connector-java-5.1.32]$ cp mysql-connector-java-5.1.32-bin.jar /home/jifeng/hadoop/hive-0.12.0-bin/lib [jifeng@jifeng02 mysql-connector-java-5.1.32]$ cd .. [jifeng@jifeng02 ~]$ cd /home/jifeng/hadoop/hive-0.12.0-bin/lib [jifeng@jifeng02 lib]$ rm mysql-connector-java-5.1.6-bin.jar
問題解決了，估計是mysql的bug吧

[jifeng@jifeng02 hive-0.12.0-bin]$ hiveLogging initialized using configuration in jar:file:/home/jifeng/hadoop/hive-0.12.0-bin/lib/hive-common-0.12.0.jar!/hive-log4j.properties hive> show tables; OK t1 tianq tianqi Time taken: 2.182 seconds, Fetched: 3 row(s) hive> drop table t1; OK Time taken: 1.02 seconds hive> select * from tianq; OK Time taken: 0.192 seconds hive> drop table tianq; OK Time taken: 0.28 seconds

總結

以上是生活随笔為你收集整理的hive中删除表的错误Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException的全部內容，希望文章能夠幫你解決所遇到的問題。
