[~dongjoon] Thanks for the fix. Just to clarify, does this mean that the fix
will only be in 2.0.0 and not in 1.6.4 (assuming there will be a 1.6.4 release)?

[jira] [Created] (SPARK-18709) Failure to throw error and automatic null conversion bug when creating a Spark Datarame with incompatible types for fields.
Amogh Param created SPARK-18709:
---
Summary: Failure to throw error and automatic null conversion bug
when creating a Spark Datarame with incompatible types for fields.
Key: SPARK-18709
URL: https://issues.apache.org/jira/browse/SPARK-18709
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.6.3, 1.6.2
Reporter: Amogh Param
Fix For: 2.0.2
When converting an RDD with a `float` type field to a spark dataframe with an
`IntegerType` / `LongType` schema field, spark 1.6.2 and 1.6.3 silently convert
the field values to nulls instead of throwing an error like `LongType can not
accept object ___ in type `. However, this seems to be fixed in
Spark 2.0.2.
The following example should make the problem clear:
{code}
from pyspark.sql.types import StructField, StructType, LongType, DoubleType
schema = StructType([
StructField("0", LongType(), True),
StructField("1", DoubleType(), True),
])
data = [[1.0, 1.0], [nan, 2.0]]
spark_df = sqlContext.createDataFrame(sc.parallelize(data), schema)
spark_df.show()
{code}
Instead of throwing an error like:
{code}
LongType can not accept object 1.0 in type
{code}
Spark converts all the values in the first column to nulls
Running `spark_df.show()` gives:
{code}
++---+
| 0| 1|
++---+
|null|1.0|
|null|1.0|
++---+
{code}
For the purposes of my computation, I'm doing a `mapPartitions` on a spark data
frame, and for each partition, converting it into a pandas data frame, doing a
few computations on this pandas dataframe and the return value will be a list
of lists, which is converted to an RDD while being returned from
'mapPartitions' (for all partitions). This RDD is then converted into a spark
dataframe similar to the example above, using `sqlContext.createDataFrame(rdd,
schema)`. The rdd has a column that should be converted to a `LongType` in the
spark data frame, but since it has missing values, it is a `float` type. When
spark tries to create the data frame, it converts all the values in that column
to nulls instead of throwing an error that there is a type mismatch.
