> We have read a file and created a PCollection of Strings where each record
> represent one line on the file. There after we have multiple PTransforms to
> validate the records. In the end The Pcollection was filtered into two
> PCollection , one with all valid records and one with all invalid records.
> Now both the pcollections are stored to respective mongo db collections . In
> case if any of these pcollection is empty we are facing below exception trace
> :
