-------------------------------------

Sounds good [~stevel@apache.org]. I am all for code reuse and consistency.

> Useful when distcp needs to access 2 Data Lake stores with different SPIs.
> Of course, a workaround is to grant the same SPI access permission to both stores, but
sometimes it might not be feasible.
> One idea is to embed the store name in the configuration property names, e.g., {{dfs.adls.oauth2.<store>.client.id}}.
Per-store keys will be consulted first, then fall back to the global keys.
