HDP 2.5: Falcon Hive Feed truncate table data

New Contributor

I was trying the use case provide in the below URL using Falcon,

https://dzone.com/articles/apache-falcon-defining-a-process-with-multiple-hiv

2 Input Hive Table Feed and 1 Output Hive Table Feed.

Use case: table name and count the number of records based on feed_date partition column in the output table.

Issue:

Once I submit the input and output Hive Tables Feed. Data/Records are truncated from both Input table.

What I want is, Input tables records should not be evicted/truncated.

Is there any better use case like above to practice Falcon with Hive?. I can not find use cases for Falcon except Hortonwork tutorial.

Thanks,

Uvaraj
