在啟動hive建立表的時候，興許你們回碰到這個錯誤：http://blog.csdn.net/qq_35732963/article/details/54139581；百度一下，說是字元編碼的問題，那個好解決，但是下面這個錯，卻不一樣，歸根到底是資料庫出了問題！

1、上傳資料到hive表時報錯：

hive> load data local inpath '/home/hadoop/data1.txt' into table partition_tablespartition(gender='M');
Loading data to table hive1.partition_tables partition (gender=M)

Failed with exception MetaException(message: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.

)
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MoveTask

2、說到底還是改下資料庫方面的：刪除原先自動建立的hive資料庫，新建metastore資料庫

mysql> create database metastore;
Query OK, 1 row affected (0.01 sec)

mysql> show create database metastore;
+-----------+--------------------------------------------------------------------+
| Database  | Create Database                                                    |
+-----------+--------------------------------------------------------------------+
| metastore | CREATE DATABASE `metastore` /*!40100 DEFAULT CHARACTER SET utf8 */ |
+-----------+--------------------------------------------------------------------+
1 row in set (0.00 sec)
mysql> alter database metastore  character set latin1;
Query OK, 1 row affected (0.00 sec)

3、去hadoop使用者下修改hive/conf裡面的hive-site.xml

這裡原本是hive的資料庫，但由於報錯,把原來的hive'刪了，新建一個metastore

[[email protected] conf]$ vi hive-site.xml

<!-- metadata database connection configuration -->
<property>
  <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost:3306/metastore?createDatabaseIfNotExist=true</value>   ----這個引數使用來設定元資料連線字串
    <description>JDBC connect string for a JDBC metastore</description>
</property>

4、 ---給建立的2個檔案 許可權

[[email protected] hadoop]# ll  
total 76
drwxrwxr-x.  4 hadoop hadoop 4096 Dec 26 19:30 app
-rw-r--r--   1 hadoop hadoop   55 Jan  9 19:12 data1.txt
-rw-r--r--   1 root   root     44 Jan  9 19:13 data2.txt

[[email protected] hadoop]# chgrp hadoop data2.txt
[[email protected] hadoop]# chown hadoop data2.txt

5、啟動hive

[[email protected] conf]$ hive
Logging initialized using configuration in file:/home/hadoop/hive-0.14.0/conf/hive-log4j.properties
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/hadoop/hadoop-2.6.2/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/hadoop/hive-0.14.0/lib/hive-jdbc-0.14.0-standalone.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

hive> create database hive1;
OK
Time taken: 0.415 seconds
hive> create table partition_tables
    > (tid int,tname string, age int)
    > partitioned by (gender string)
    > row format delimited fields terminated by ',';
OK
Time taken: 0.328 seconds

6、再次上傳檔案到分割槽表，顯示上傳成功

hive> load data local inpath '/home/hadoop/data1.txt' into table partition_tables partition(gender='M');
Loading data to table default.partition_tables partition (gender=M)
Partition default.partition_tables{gender=M} stats: [numFiles=1, numRows=0, totalSize=55, rawDataSize=0]
OK
Time taken: 1.138 seconds

hive>  load data local inpath '/home/hadoop/data2.txt' into table partition_tables partition(gender='F');
Loading data to table default.partition_tables partition (gender=F)
Partition default.partition_tables{gender=F} stats: [numFiles=1, numRows=0, totalSize=44, rawDataSize=0]
OK
Time taken: 0.661 seconds

7、進入http://master:50070/檢視partition_table分割槽是否成功
