Hello Alexey Serbin, Yuqi Du, Yingchun Lai, Yifan Zhang, Kudu Jenkins, KeDeng,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#13).
Change subject: KUDU-3452 Create tablet without enough healthy tservers
......................................................................
KUDU-3452 Create tablet without enough healthy tservers
Currently, creating a three-replicas table when there are
not enough tablet servers will fail and the system catalog
will retry continuously and always fail until the unavailable
tablet servers becomes healthy again.
An under-replicated table is still available for reading and
writing, so it's enough to place just a majority of replicas
for each tablet at healthy tablet servers to make a newly
created table ready to use.
This patch adds a new flag:
--allow_creating_under_replicated_tables to support this
feature. The original logic is kept the same. When this flag
is set true, it's possible to create a tablet placing just a
majority of replicas at healthy tablet servers. Even if the
new tablet is created under-replicated, it's still available
for read and write operations.
