Can't collect edr-log and store it in HDFS using nifi

Question

1. I'm trying to collect the logs from EDR and store it in hdfs using NIFI using the following nifi dataflow: Its working well but the size of the stored file was so small though I combined records together

 {the fist dataflow I created ](https://i.stack.imgur.com/g9AyX.png)

configuration of listenUDP

2. I intended to merge records before do the compression but the merge process not receiving data from the listenUDP processor

3. I tried listenUDP record instead of listenUDP but it didn't listen to any data

Second dataflow configuration of mergerecod processor

any suggested solution

suggested solution, what's wrong with what I did?
