Steve Loughran commented on HDFS-14939:
---------------------------------------
Proposed
* you define a a new capability for PathCapabilities; those stores which
implement setQuota return true.
* FilterFileSystem to forward the new methods to the wrapped FS.
* ViewFileSystem to forward to the wrapped FS
* Something in Filesystem.md which defines quotas and what setting/getting
means. Something about who is permitted to set them in a secure cluster too.
* a (minimal) abstract contract test for setQuota designed to explore the
failure conditions: negative numbers, quota of 2^63-1, ..., invalid path,
relative path.
FileContext also needs to be looked that, primarily by adding the same methods
in FileContext, invoking AbstractFileSystem etc etc. Nothing hard, just extra
housekeeping.
> Update documnet and UT tests for Quota API.
