报错如下： 2022-02-21 18:07:56,595 FATAL [IPC Server handler 22 on 42371] org.apache.hadoop.mapred.TaskAttemptListenerImpl: Task: attempt_1639734219463_44543_m_000001_0 - exited : java.io.IOException: java.sql.SQLException: ORA-12592: TNS:bad packet at org.apache.sqoop.mapreduce.AsyncSqlRecordWriter.write(AsyncSqlRecordWriter.java:233) at org.apache.sqoop.mapreduce.AsyncSqlRecordWriter.write(AsyncSqlRecordWriter.java:46) at org.apache.hadoop.mapred.MapTask$NewDirectOutputCollector.write(MapTask.java:658) at org.apache.hadoop.mapreduce.task.TaskInputOutputContextImpl.write(TaskInputOutputContextImpl.java:89) at org.apache.hadoop.mapreduce.lib.map.WrappedMapper$Context.write(WrappedMapper.java:112) at org.apache.sqoop.mapreduce.hcat.SqoopHCatExportMapper.map(SqoopHCatExportMapper.java:56) at org.apache.sqoop.mapreduce.hcat.SqoopHCatExportMapper.map(SqoopHCatExportMapper.java:35) at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:146) at org.apache.sqoop.mapreduce.AutoProgressMapper.run(AutoProgressMapper.java:64) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:787) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:341) at org.apache.hadoop.mapred.YarnChild$2.run(YarnChild.java:170) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1869) at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:164)查找资料，很多建议： 数据容量、超时时间、防火墙 。 挨个排查，使用CSV数据往Oracle同步，发现没问题。 最终确定是数据格式的原因： 某些字段有特殊字符，比如按了 TAB键，空格键等。 表中查找是否含有特殊字符的字段，尤其是备注字段，姓名字段，诸如此类需要手输的字段，因为业务前端录入可能会有这样的问题。 |
