在使用sqoop工具对hive表导出到mysql中提示该信息，一直重试。通过网上查阅资料，这个问题是指定hdfs路径不严谨导致。

报错写法

sqoop export --connect jdbc:mysql://c6h2:3306/log --username root --password 123 --table dailylog --fields-terminated-by '\001' --export-dir '/user/hive/warehouse/weblog_2013_05_30'

解决方法

sqoop export --connect jdbc:mysql://c6h2:3306/log --username root --password 123 --table dailylog --fields-terminated-by '\001' --export-dir 'hdfs://cluster1/user/hive/warehouse/weblog_2013_05_30'

这里加上hdfs协议和集群名称，我这里是hadoop2的ha集群模式。
