Github user steveloughran commented on the issue:
https://github.com/apache/hadoop/pull/339
apart from the comments inline, I've got nothing else to add...lets see
what yetus says. Good to see from the cloudstore test that the option
provenance is being set, as it will help debugging in a world where things get
more complex
> ADLS to support per-store configuration
> ---------------------------------------
>
> 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.
