sqoop export:java.lang.RuntimeException: Can't parse input data

使用sqoop从hive导出数据到mysql发生如下错误：
sqoop export –connect jdbc:mysql://192.168.38.64:3306/test –username root -P –table mytable –input-null-string ‘\N’ –export-dir /user/hive/warehouse/test.db/mytable

Error: java.io.IOException: Can't export data, please check failed map task logs

这是因为 没有指定null字段分隔符，导致错位。

sqoop export –connect jdbc:mysql://192.168.38.64:3306/test –username root -P –table mytable –input-null-string ‘\N’ –input-null-non-string ‘\N’ –input-fields-terminated-by ‘\001’ –export-dir /user/hive/warehouse/test.db/mytable

测试成功。
