sqoop从hdfs导入数据到mysql疑问 5C

需求:需要实现从sqlserver库中导入数据到mysql中,但实际上只导入了1条记录就结束了(实际数据600+条)。

查看了原因: 应该就是行分隔符引起了 只导入了一条就结束了 。

代码:

1、通过sqoop脚本将sqlserver导入到hdfs中:

sqoop import \
--connect "jdbc:sqlserver://192.168.1.130:1433;database=测试库" \
--username sa \
--password 123456 \
--table=t_factfoud \
--target-dir /tmp/sqoop_data/900804ebea3d4ec79a036604ed3c93a0_2014_yw/t_factfoud9 \
--fields-terminated-by '\t' --null-string '\N' --null-non-string '\N' --lines-terminated-by '\001' \
--split-by billid -m 1

2、通过sqoop脚本将hdfs数据导出到mysql中:

sqoop export \
--connect 'jdbc:mysql://192.168.1.38:3306/xiayi?useUnicode=true&characterEncoding=utf-8' \
--username root \
--password 123456 \
--table t_factfoud \
--export-dir /tmp/sqoop_data/900804ebea3d4ec79a036604ed3c93a0_2014_yw/t_factfoud9 \
-m 1 \
--fields-terminated-by '\t' \
--null-string '\N' --null-non-string '\N' \
--lines-terminated-by '\001'

现在执行结果:
1、sqlserver库中 表 t_factfoud 中有 600 条记录,已正确到到hdfs中 。
2、从hdfs导出到mysql,只正确导入了一条,就结束了。

效果图如下:

提醒一下,你的数据没有脱敏就这样放上来不太好。我们做项目的首先考虑的就是数据安全性。多嘴了,勿怪。

--lines-terminated-by '\001'
你确定导入的数据是以这个 为行分隔符吗,
hadoop dfs -cat /tmp/sqoop_data/900804ebea3d4ec79a036604ed3c93a0_2014_yw/t_factfoud9/* > temp.dat

看下文件temp.dat 是怎么分行的。

另外建议看下 sqoop 文档 --lines-terminated-by 是否 import 和 export 都支持

sqoop2数据导入相关疑问

场景: 通过 sqoop2, 从oracle 数据导入 hdfs 问题1)当oracle表中有blob字段的列时出现类型转换失败 , Integer 不能转BigDecimal, 问题是表中没有number列也出现此问题. 问题2)sqoop2是否支持往hbase的数据导入?? , 因为connector中 没有hbase相关连接器模板 希望发下以上两个问题描述或相关资料连接地址 注: 时 sqoop2 相关资料. 别发sqoop1的资料

在使用sqoop从hive往mysql导数时,脚本命令也增加了--input-null-string '\\N' --input-null-non-string '\\N'。当第一个字段为null,导出失败;当第一个字段不为null,其他字段为null,导出成功。 请问,这是怎么回事?该如何解决?

通过sqoop导出hive ORC格式表,是否可以不用启动Hive Metastore?

kerberos环境中,通过sqoop+hcatlog导出hive ORC格式表,是否可以不用启动Hive Metastore? 通过测试发现:在没有kerberos安全认证的环境下,通过sqoop导出ORC格式的数据时不用启动Hive Metastore。 但是在kerberos安全认证的环境下,通过sqoop导出hdfs上的ORC格式的数据就必须启动Hive Metastore。 有没有一种解决方法,在kerberos安全认证环境下导出ORC数据不用启动Hive Metastore?

求救高手,Mapreduce导入数据到Hadoop报ClassNotFoundException

最近在用Mapreduce连Hadoop,出现各类问题。请高手答疑。 环境: hadoop:2.7.0 Hbase:1.0.1.1 刚开始的时候报:HBaseConfiguration 找不到,百度之,说将 hbase的lib下的jar复制到hadoop的lib下 复制之,无果,找各类参考资料修改hadoop参数,都还是报异常。 最后无奈,只能修改 hadoop-env.sh,将 hbase 的lib加入到 classpath下。 ![图片说明](https://img-ask.csdn.net/upload/201509/14/1442242731_955123.jpg) 最后终于不报这个异常。 可是接着更加无解的事情发生了。 ![图片说明](https://img-ask.csdn.net/upload/201509/14/1442242933_762859.jpg) 报出各类我自己定义的类找不到。 网上找遍了所有的贴,没找到答案。 ``` public static void main(String[] args) throws Exception { Configuration conf = new Configuration(); conf = HBaseConfiguration.create(conf); if (args.length != 6) { System.err.println("Usage: MroFormat <in-mro> <in-xdr> <sample tbname> <event tbname>"); System.exit(2); } //makeConfig(conf, args); String inpath1 = args[0]; String inpath2 = args[1]; Job job = Job.getInstance(conf,"MyTest"); job.setNumReduceTasks(40); job.setJarByClass(Main.class); job.setReducerClass(ReduceDeal.MroFormatReducer.class); //job.setReducerClass(ReduceDeal.TestReducer.class); job.setSortComparatorClass(MapDeal.SortKeyComparator.class); job.setPartitionerClass(MapDeal.CellIDPartitioner.class); job.setGroupingComparatorClass(MapDeal.SortKeyGroupComparator.class); job.setMapOutputKeyClass(CellTimeKeyPare.class); job.setMapOutputValueClass(Text.class); MultipleInputs.addInputPath(job, new Path(inpath1), KeyValueTextInputFormat.class, MapDeal.MroMapper.class); MultipleInputs.addInputPath(job, new Path(inpath2), TextInputFormat.class, MapDeal.XdrMapper.class); job.setOutputFormatClass(MultiTableOutputFormat.class); //job.setOutputFormatClass(NullOutputFormat.class); //LOG.info(job.getPartitionerClass().getName()); //TableMapReduceUtil.addDependencyJars(job); //TableMapReduceUtil.addDependencyJars(job.getConfiguration()); //TableMapReduceUtil.initTableReducerJob("tab1", ReduceDeal.MroFormatReducer.class, job); System.exit(job.waitForCompletion(true) ? 0 : 1); } ``` 在本机的win7环境下,代码能跑过,但打包放到服务器就报错,找不着类。去掉了“conf = HBaseConfiguration.create(conf);”这段代码后,下面的 处理类就可以找到。请大牛们帮忙看看,非常感谢
