hive 问题总结

1. org.apache.hadoop.hive.ql.metadata.HiveException: MetaException(message:Exception thrown when executing query 

FAILED: SemanticException org.apache.hadoop.hive.ql.metadata.HiveException: 
MetaException(message:Exception thrown when executing query :
 SELECT DISTINCT 'org.apache.hadoop.hive.metastore.model.MPartition' 
AS `NUCLEUS_TYPE`,`A0`.`CREATE_TIME`,`A0`.`LAST_ACCESS_TIME`,`A0`.`PART_NAME`,`A0`.`PART_ID`,`A0`.`PART_NAME` AS `NUCORDER0` FROM `PARTITIONS` `A0` LEFT OUTER JOIN `TBLS` `B0` ON `A0`.`TBL_ID` = `B0`.`TBL_ID` LEFT OUTER JOIN `DBS` `C0` ON `B0`.`DB_ID` = `C0`.`DB_ID` WHERE `B0`.`TBL_NAME` = ? AND `C0`.`NAME` = ? ORDER BY `NUCORDER0`)

原因分析：这个错误网上情况查的都不相同，这次遇到的是磁盘满了，导致，查询去mysql中查找元素据报错，将select中的？号替换成对应的表名和库名，在元数据库mysql中查询一下，就可以看到明显的错误提示

SELECT `A0`.`PART_NAME`,`A0`.`PART_NAME` AS 
`NUCORDER0` FROM `PARTITIONS` `A0` LEFT OUTER JOIN `TBLS` `B0` ON `A0`.`TBL_ID` 
= `B0`.`TBL_ID` LEFT OUTER JOIN `DBS` `C0` ON `B0`.`DB_ID` = 
`C0`.`DB_ID` WHERE `C0`.`NAME` = '库名' AND `B0`.`TBL_NAME` = '表名' ORDER BY `NUCORDER0`

解决方案：清理磁盘空间
