Christopher Tubbs commented on ACCUMULO-4087:
---------------------------------------------
Using the "sticky" (previously chosen volume for that tablet) could work. I'm
not a big fan of the sticky volume behavior.
Another option, instead of using the previously chosen one, is to pull the
table id from the {{KeyExtent}}, and re-choose with the appropriate chooser for
that table (assuming the per-table chooser is configured as the general
chooser). That might save some work examining the tablet's metadata, but at the
risk of choosing another location (which is probably fine anyway). Of course,
that only works if the {{FileUtils}} code is only being used for tablet- or
table-scoped temp files, and not also used for general-purpose temp files (do
we even have any such files? intermediate write-ahead logs? if we do, do they
use this code?).

> 4. The volume chooser is called in {{FileUtils}} for temp directory creation

> needing the volume chooser at all.
