sqoop1.4.7之删除时事务异常

当mysql的binlog_format=STATEMENT 是，sqoop执行以下删除语句异常：

sqoop eval \
--connect 'jdbc:mysql://*:3306/yn_hadoop?useUnicode=true&characterEncoding=utf-8' \
--username ynhadoop \
--password * \
--query "delete from video_user_count_rank_day where t_date>='2020-08-03' and t_date<'2020-08-04';";

sqoop对mysql进行按条件查询删除时，报transaction isolation level is READ COMMITTED or READ UNCOMMITTED；如下：

2020-08-14 14:42:53,064 WARN tool.EvalSqlTool: SQL exception executing statement: java.sql.SQLException: Cannot execute statement: impossible to write to binary log since BINLOG_FORMAT = STATEMENT and at least one table uses a storage engine limited to row-based logging.

通过获取sqoop执行eval事务级别发现默认是读-提交；而mysql数据库默认是REPEATABLE_READ；

解决办法有以下几种：

1、修改mysql 全局变量：

mysql> SET GLOBAL binlog_format=ROW; （也可设置为MIXED模式）

2、修改mysql配置my.cnf文件：

binlog_format=ROW; （也可设置为MIXED模式）

3、sqoop参数配置（推荐使用）

sqoop eval \
--connect 'jdbc:mysql://*:3306/yn_hadoop?useUnicode=true&characterEncoding=utf-8' \
--username ynhadoop \
--password * \
--metadata-transaction-isolation-level 'TRANSACTION_REPEATABLE_READ' \
--query "delete from video_user_count_rank_day where t_date>='2020-08-03' and t_date<'2020-08-04';";
