[CARBONDATA-668] Dataloads fail when no. of column in load query is
greater than the no. of column in create table
Problem: Dataloads fail when no. of column in load query is greater than
the no. of column in create table
Analysis: During data load mapping of columns order is maintained between
schema and columns provided in Fileheader/CSV file. If any duplicate column is
provided in the fileheader, the length of array exceeds for the mapping order
array as extra columns are getting matched and hence array index of bound
exception is thrown.
Fix: Add a check for looping only till the mapping order array length is
less than the number of schema columns.
Impact Area: Data load flow
