Barry Becker commented on SPARK-17039:
--------------------------------------
There are literal ?'s in the datafile. The "nullValue" option indicates that
those ?'s should be read as null values. I also added the "dateFormat" option
which describes how the dates in the file should be read.
Let me try to provide more information so you can reproduce.
Here is the schema that I am specifiying (dfSchema above):
{code}
StructType(StructField(string normal,StringType,true),
StructField(Years,TimestampType,true), StructField(Months,TimestampType,true),
StructField(WeekDays,TimestampType,true), StructField(Days,TimestampType,true),
StructField(DaysWithNull,TimestampType,true),
StructField(Hours,TimestampType,true), StructField(Minutes,TimestampType,true),
StructField(normal dates,TimestampType,true), StructField(Wide Range
Dates,TimestampType,true), StructField(Narrow,TimestampType,true),
StructField(Far Future,TimestampType,true), StructField(Mostly
Null,TimestampType,true), StructField(All Same Date,TimestampType,true),
StructField(Past/Future,TimestampType,true), StructField(All
nulls,TimestampType,true), StructField(Seconds,TimestampType,true))
{code}
and here is the contents of the csv datafile (note that there are lots of
nulls). This worked using databricks spark-csv lib as a dependency in spark
1.6.2
{code}

> Project: Spark
> Issue Type: Bug
> Components: Input/Output
> Affects Versions: 2.0.0
> Reporter: Barry Becker
>
> I see this exact same bug as reported in this [stack overflow
> post|http://stackoverflow.com/questions/38265640/spark-2-0-pre-csv-parsing-error-if-missing-values-in-date-column]
> using Spark 2.0.0 (released version).
> In scala, I read a csv using
> sqlContext.read
> .format("csv")
> .option("header", "false")
> .option("inferSchema", "false")
> .option("nullValue", "?")
> .option("dateFormat", "yyyy-MM-dd'T'HH:mm:ss")
> .schema(dfSchema)
> .csv(dataFile)
> The data contains some null dates (represented with ?).
> The error I get is:
> {code}
> org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in
> stage 8.0 failed 1 times, most recent failure: Lost task 0.0 in stage 8.0
