回复：[Bug] dataframe.show() prints incorrect numbers

[zzuly2010 <zz...@163.com>]

Hi,


     Maybe you can use the show(truncate: Boolean)  API to display your data.

What is the right process for reporting this bug in spark?
 
SUMMARY: For some small numbers, dataframe.show() chops off the exponential field showing wrong numbers instead.
 
HOW TO REPRODUCE THE BUG: This is a one-liner on the command line:
echo 'Seq((1.8181682328650097E-4)).toDF("x").show()' | docker run -i apache/spark /opt/spark/bin/spark-shell
 
WHAT IS THE OUTPUT:
scala> Seq((1.8181682328650097E-4)).toDF("x").show()
+--------------------+
|                   x|
+--------------------+
|1.818168232865009...|
+--------------------+
 
WHAT SHOULD BE THE CORRECT OUTPUT:
scala> Seq((1.8181682328650097E-4)).toDF("x").show()
+--------------------+
|                   x|
+--------------------+
|1.818168232865009E-4|
+--------------------+
 
 
Please advise how to report this bug.
