Benoit Chesneau commented on COUCHDB-1667:
------------------------------------------

I think the idea was to fix a common base index dir for all indexers. So index_dir would be better for the future imo. I would prefer a change that put index_dir as default but if view_index_dir is set (ie in local.ini for old versions) choose that one. Would it it be OK for you?

Whatever the choice we do maybe we could print a warning in case both are present? And highlight the one that should be used?

> CouchDB 1.3 ships with new couch_index app[1] that uses `index_dir` config option to locate directory to store view indexes. However, it replaces[2] old `view_index_dir`option creating situation when recently updated default.ini will have only `index_dir` option and old, but production used local.ini would still have `view_index_dir`. There is a fallback[3], but there no insurance that it will let user gracefully update.
> This situation may leads to very bad situations, when all indexes will be rebuilded against location that may not expects their on disk size (since `view_index_dir` was pointed to the another mount point) which leads to server fall.
