Ingesting Drifting Data into Hive and Impala
Importing data into Apache Hive is one of the most common use cases in big data ingest, but gets tricky when data sources ‘drift’, changing the schema or semantics of incoming data. Introduced in StreamSets Data Collector (SDC) 1.5.0.0, the Hive Drift Solution monitors the structure of incoming data, detecting schema drift and updating the Hive Metastore accordingly, allowing data to keep flowing. In this blog entry, I’ll give you an overview of the Hive Drift Solution and explain how you can try it out for yourself, today.
