Subject 答复: upgrade from 3.9 to 3.11.2
Date Thu, 03 May 2018 07:12:04 GMT
Thanks Hannu,
Another question is that,do I need to stop the frontend application during the upgrade?
I have 3 nodes cluster,let’s say:
Cassandra01
Cassandra02
Cassandra03

First I upgrade the cassandra01 node,
1,nodetool drain
2,backup data
3,install new binary
4,configure the configuration file
5,start Cassandra service
6,nodetool upgrade

Then another node one by one

do I need to stop the frontend application during the upgrade?

Hello,

it never hurts to run “nodetool upgradesstables" after the upgrade. It’s a no-op if there
is nothing to upgrade.

Hi Community
  I have a question regarding upgrading Cassandra from 3.9 to 3.11.2,
  Do I need to run nodetool upgradesstables when I do the upgrade?we know that we don’t
need to run this command when we do minor version upgrade.But from 3.9 to 3.11.2,I have no
idea.
  Also I suggest that the community should have official article about the upgrading,everytime
I do upgrade we can just google the posts via internet.
