How can I combine(concatenate) two data frames with the same column name in java

Question

Can I append a dataframe to the right of other dataframe having same column names

Answer 1

You can join two dataframes like this.

df1.join(df2, df1.col("column").equalTo(df2("column")));

If you are looking for Union, then you can do something like this.

df1.unionAll(df2);  // spark 1.6

Spark 2.0, unionAll was renamed to union
