I want save some data in hive through fiware-cygnus, but we occured some problems;

I guess the difference between hive table column name and HDFS File Attribute Name is the problem. Hive table column name used encoding name, but hdfs file attribute name use not encoding name.(ex: recvTimeTs - recvx0054imex0054s)

How to match between Hive Table Column name and HDFS File Attribute name?

or How to use cygnus and hive other way?
