Todd Lipcon commented on KUDU-2975:
-----------------------------------
agreed this would be good to do. I think [~awong] had done some
investigation/write-up of what would be required to do this at one point, right?

> Recently, we deployed a new kudu cluster and every node has 12 SSD. Then, we
> created a big table and loaded data to it through flink. We noticed that the
> util of one SSD which is used to store WAL is 100% but others are free. So,
> we suggest to spread WAL across multiple data directories.
