@ShawnWalker I reviewed this and talked with @keith-turner some. I imagine
during a rolling upgrade the process would be.
- Stage the new install on the box
- Run stop-here.sh
- Reconfigure the node to use the new install
- Run start-here.sh
The stop-here.sh command has the master unload the tablets I think. How
will this patch handle that case?
When a tablet server is suspended, all queries will block right? I see you
are suspending the metadata tablets too. That will affect more than just a
user queries though. Bulk imports trying to get hosted locations comes to
mind. I see you are not suspending the root tablet though.
I see you are storing the host and port in the metadata for a suspended
tablet. Sometimes we have tservers come up with a different host or port. In
that case, I guess the tablets will wait until the suspend duration to be
reassigned.
