HIVE 常見錯誤

參考以前的hive測試步驟一一執行。

hive> drop table sansom;
FAILED: Error in metadata: org.apache.thrift.transport.TTransportException
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

 

若是出現
FAILED: Error in metadata: javax.jdo.JDODataStoreException: Error(s) were found while auto-creating/validating the datastore for classes. The errors are printed in the log, and are attached to this exception.
NestedThrowables:
com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Specified key was too long; max key length is 1000 bytes
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

或者是
FAILED: Error in metadata: MetaException(message:Got exception: org.apache.thrift.transport.TTransportException null)
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

以上錯誤，主要是在select操做、drop操做時，就會出錯。

這樣的錯誤，能夠修改hive數據庫編碼:

mysql> alter database hivedb character set latin1;

而後重啓hive metastore和hive server就能夠了

mysql數據庫的編碼目前最好設置爲latin1,不然使用hive會出現莫名其妙的問題

如何仍是不行，能夠使用 

DEBUG命令：

hive -hiveconf hive.root.logger=DEBUG,console

來排錯！
