----------------------------------
I'm so sorry to have seen this so far.
Thanks for your recommendation, i will read carefully about contributing.
Spark 2.2 have a great diffrence from Spark 2.0, I have checked Spark 2.2-rc4,
it seems to have no change about this. when get a serde, it also set null to
first parameter Configuration, so we can't get any conf from initialize, the
link is:
https://github.com/apache/spark/blob/v2.2.0-rc4/sql/hive/src/main/scala/org/apache/spark/sql/hive/execution/HiveFileFormat.scala#L119
> Add hive configuration when initialize hive serde in InsertIntoHiveTable.scala

> When case class InsertIntoHiveTable intializes a serde it explicitly passes
> null for the Configuration in Spark 1.5.0:
> [https://github.com/apache/spark/blob/v1.5.0/sql/hive/src/main/scala/org/apache/spark/sql/hive/execution/InsertIntoHiveTable.scala#L58]
> While in Spark 2.0.0, the HiveWriterContainer intializes a serde it also just
> passes null for the Configuration:
> [https://github.com/apache/spark/blob/v2.0.0/sql/hive/src/main/scala/org/apache/spark/sql/hive/hiveWriterContainers.scala#L161]
> When we implement a hive serde, we want to use the hive configuration to get
> some static and dynamic settings, but we can not do it !
> So this patch add the configuration when initialize hive serde.
