---------------------------------
Summary: Add/Replace some Java friendly DataFrame API
Key: SPARK-10270
URL: https://issues.apache.org/jira/browse/SPARK-10270
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Cheng Hao
Currently in DataFrame, we have API like:
{code}
def join(right: DataFrame, usingColumns: Seq[String]): DataFrame
def dropDuplicates(colNames: Seq[String]): DataFrame
def dropDuplicates(colNames: Array[String]): DataFrame
{code}
Those API not like the so friendly to Java programmers, change it to:
{code}
def join(right: DataFrame, usingColumns: String*): DataFrame
def dropDuplicates(colNames: String*): DataFrame
{code}
