Work Description: Hexiaoqiao commented on pull request #2288:
URL: https://github.com/apache/hadoop/pull/2288#issuecomment-694635082
> 2. If users mistakenly configured multiple archive paths on the same
mount, it will throw an error msg (as per [this
line).](https://github.com/apache/hadoop/pull/2288/files#diff-8aa3c5049e8a5394bea1aa107dd87d30R339)
But yes the capacity will not be reported correctly in this case. Please let
me know what do you think, we can probably just exit DN and let users fix the
config.
Thanks @LeonGao91 , this is indeed my concern, I think only log is not
proper way, because the following logic will be not correct, especially the
capacity remains if mis-config. FYI, Thanks.
