Grant Henke commented on KUDU-1592:
-----------------------------------
I think that would require addingÂ
_[--unlock_unsafe_flags|https://kudu.apache.org/docs/configuration_reference.html#kudu-master_unlock_unsafe_flags]_
on upgrade or it would break existing deployments.
> Documentation that mentions file block manager should sound more ominous

> In troubleshooting.adoc, as well as in the error message when we fail to hole
> punch, we suggest using the file block manager as a workaround. It says
> something vague about "at the cost of some scalability and efficiency" but
> should be something a lot more ominous -- users are quickly running out of
> file descriptors if they try the FBM.
