I have log where duplicate field name occurs with same values. while parsing that csv file just want to entertain single field and their values.
e.g. Fields_A |Fields_B| Fields_A| Fields_C
Just want Fields_A| Fields_B| Fields_C to output elasticsearch.
how to assign string for the fields having null values. I want to replace field values with some string if they have null values and output them to elastic search.
Any help is much appreciated.
