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.
