QUESTION : For an existing data source created with granularity MONTH, and where during Hadoop ingestion Admin changes the granularity to DAY. What will be the resultant granularity on the data source?
ANSWER : Datasources can contain segments of different granularity, and the granularity of a particular datasource depends on ingestion configuration. so the new segments from a Hadoop job will have DAY granularity and the previously generated segments will continue to have MONTH granularity.
