> Support for inferring type date/timestamp/decimal for partition column
> ----------------------------------------------------------------------
>
> Key: SPARK-17388
> URL: https://issues.apache.org/jira/browse/SPARK-17388
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Hyukjin Kwon
> Fix For: 2.1.0
>
>
> Currently, Spark only supports to infer {{IntegerType}}, {{LongType}},
> {{DoubleType}} and {{StringType}}.
> {{DecimalType}} is being tried but it seems it never infers type as
> {{DecimalType}} as {{DoubleType}} is being tried first.
> Also, {{DateType}} and {{TimestampType}} can be inferred. It seems it is a
> pretty common to use both for a partition column.
> It'd be great if they can be inferred as both rather than just {{StringType}}.
