> Currently, the WAL and the StoreFiles need to be on the same FileSystem. Some
> FileSystems (such as Amazon S3) don’t support append or consistent writes.
> These two properties are imperative for the WAL in order to avoid loss of
> writes. However, StoreFiles don’t necessarily need the same consistency
> guarantees (since writes are cached locally and if writes fail, they can
> always be replayed from the WAL).
>
> This JIRA aims to allow users to configure a log directory (for WALs) that is
> outside of the root directory or even in a different FileSystem. The default
> value will still put the log directory under the root directory.
