title: sqoop export oracle number col RuntimeException: Can't parse input data: '1.0'
body: <p>I want to export a text table file (input fields terminated by '\t', and I save it to hdfs use pyspark.DataFrame.write.csv('output_history_with_ta_text', sep='\t')) from hdfs to an oracle DB's table.
  The table has a col named training_accuracy and the type is NUMBER (Just NUMBER, not NUMBER(n,m)  ).
  but I met this problem:</p>
