Hi, Currently, for the usecases involving writing POJO to file output we use DAG simillar to following: POJOEmittingOperator->CSVFormatter->StringFileOutputOperator.
Both CSVFormatter as well as StringFileOutputOperator have configurable tupleSeperator defaulting to newline. This introduces two newlines for every tuple. We should make one of the defaults to empty string and the other to be newline. Any opinions on which default should be empty string? ~ Yogi
