-------------------------------
Summary: Support drop multiple columns specified by Column class
in DataFrame API
Key: SPARK-12227
URL: https://issues.apache.org/jira/browse/SPARK-12227
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 1.5.2
Reporter: Sun Rui
In SPARK-11884, dropping multiple columns specified by column names in the
DataFrame API was supported.
However, there are two drop variants for single column:
{code}
def drop(colName: String)
def drop(col: Column)
{code}
>From API parity's point of view, it would be better to also support dropping
>multiple columns specified by Column class.
