Rename Dataframe columns

[sunnn]

Existing Rename data frame works exactly but a new column is added at the end from the

add column

function in source code

To rectify this changes to be made in config file and filter it separately on the Scala code before passing it to the Data-frame function

[sunnn]

the above function will work in sync when used with same no. of columns in both the tables
looking for details when sync can work with tables on different no of column
