在使用sqoop工具對hive表導出到mysql中提示該信息，一直重試。通過網上查閱資料，這個問題是指定hdfs路徑不嚴謹導致。
報錯寫法
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'
解決方法
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'
這里加上hdfs協議和集群名稱，我這里是hadoop2的ha集群模式。
