> ---------------------------------------
>
> Key: HADOOP-13972
> URL: https://issues.apache.org/jira/browse/HADOOP-13972
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/adl
> Affects Versions: 3.0.0-alpha2
> Reporter: John Zhuge
> Assignee: Sharad Sonker
> Priority: Major
>
> 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.
