Chandan updated SPARK-32614:
----------------------------
Description:
In most of the data ware housing scenarios files does not have comment records
and every line needs to be treated as a valid record even though it starts with
default comment character as \u0000 or null character.Though user can set any
comment character other than \u0000, but there is a chance the actual record
can start with those characters.
Currently for the below piece of code and the given testdata where first row
starts with null \u0000
character it will throw the
eg: val df =
spark.read.option("delimiter",",").csv("file:/E:/Data/Testdata.dat");
df.show(false);
*+TestData+*
