HBase w/o Master - TTL?
Hi,
How long can HBase 0.94 RegionServers live (accept reads and writes)
without a Master?
Thanks,
Otis

Thanks! We'll have up to 2 hours without the Master. This will be fun! :)

What Lars said.
As long as client doesn't issue table schema related operations, it should
run fine.

The region servers can work until they decide they need to split a region or until one of them dies. I.e. until a global region (re-)assignment is needed.
Note, though, that the HBase client does work without a running master.

Hi,
How long can HBase 0.94 RegionServers live (accept reads and writes)
without a Master?
