Summary
Sqoop2 supports a persistent store for the sqoop entities such as the Configurables ( Connector and Driver) , Configs exposed by the Connectors, Jobs and Jobruns JobRuns/Submissions etc. The persistent store is commonly referred to as the repository. We also expose Rest APIs and shell commands to perform CRUD operations on the sqoop entities such as connectors and drivers, connector configs related to link and job information, sqoop job and its configs. Thus the persistent store comes handy in keeping a history of the sqoop entity objects created and updated over time. In order to access the persistent store with ease, we also expose a simple java based repository API that different data stores can implement to store the sqoop entity objects.
