For direct MetaStore DB connections, we don't support retries at the client level.)

做操作hive时候，对分区表加载数据。报错

使用hive导入数据到分区中报错如下：

Failed with exception MetaException(message:For direct MetaStore DB connections, we don't support retries at the client level.)
org.apache.hadoop.hive.ql.metadata.HiveException: MetaException(message:For direct MetaStore DB connections, we don't support retries at the client level.)

.......

解决:

1、在网上找了许多，发现一个解决办法，应该是hive，配置文件中取的元数据库名称有问题导致的，注：使用的是mysql作为元数据存储。

（1）删除mysql里的hive自建的hive数据库，重新创建metastore,之后修改metastore的字符集

alter database metastore character set latin1;

（2）在hive的conf目录下的hive-site.xml里修改

                javax.jdo.option.ConnectionURL
                jdbc:mysql://node1:3306/metastore?createDatabaseIfNotExist=true
                JDBC connect string for a JDBC metastore
                
 

2、是hive的lib目录下mysql驱动版本的问题

替换mysql连接驱动版本为：mysql-connector-java-5.1.47.jar
