bq. Goes too much into the depths of HDFS for me to be a safe reviewer, I'm
afraid. Trust me: it's better that way
Patch size aside, this is a minor change. Attaching
[^HDFS-12882.00.salient.txt] that omits all the automated refactoring changes
i.e., propagating the flag through the protocol and tests.
The logic for the handle is similarly unsurprising.
|| HandleOpt || allow mod || allow move || open by || check ||
| exact | 0 | 0 | path | mtime, inode |
| content | 0 | 1 | inode | mtime |
| path | 1 | 0 | path | inode |
| ref | 1 | 1 | inode | -- |

> HDFS-7878 added support for {{open(PathHandle)}}, but it only partially
> implemented the semantics specified in the contract (i.e., open-by-inodeID).
> HDFS should implement all permutations of the default options for
> {{PathHandle}}.
