I'm facing an error from which I can not understand the source.
Previously I had imported a table with the same data format, with 54 million lines to the HDFS of my Hadoop cluster .
Now I created a _View_ in my database Oracle and selected a portion of the table data. Now it has only 260k lines, however I now face this error quoted even using a similar command.
SQOOP
The error generated this here:
Error: java.io.IOException: SQLException in nextKeyValue at org.apache.sqoop.mapreduce.db.DBRecordReader.nextKeyValue (DBRecordReader.java:277) at org.apache.hadoop.mapred.MapTask $ NewTrackingRecordReader.nextKeyValue (MapTask.java:556) at org.apache.hadoop.mapreduce.task.MapContextImpl.nextKeyValue (MapContextImpl.java:80) at org.apache.hadoop.mapreduce.lib.map.WrappedMapper $ Context.nextKeyValue (WrappedMapper.java:91) at org.apache.hadoop.mapreduce.Mapper.run (Mapper.java:145) at org.apache.sqoop.mapreduce.AutoProgressMapper.run (AutoProgressMapper.java:64) at org.apache.hadoop.mapred.MapTask.runNewMapper (MapTask.java:787)

Caused by: java.sql.SQLDataException: ORA-01843: not a valid month
Previously I was able to export, also with data coming from a View , only with the complete table.
The command used was:
sqoop import --connect jdbc:oracle:thin:<meu_host:porta:instancia> --username <user> --password <pass> --table <DB.TABLE> --split-by NUM_LINHA --m 10 --target-dir /user/rodrigo/RESUMO_TABELONA 2>&1|tee import_tab_menor.txt
