RE: [EXTERNAL] Re: Upgrade using rebuild

[Durity, Sean R]

The sstable formats/versions are different. Streaming uses those formats. 
Streaming doesn’t work across major versions (for sure), and I don’t even try 
it across minor versions.

To ensure Cassandra-happiness, follow the rule:
For streaming operations (adding nodes, rebuild, repairs, etc.) have everything 
on the same version.

Version upgrades can be automated relatively easily and complete in a 
reasonable period of time. Plan them accordingly and don’t do streaming until 
they are completed.

You generally can’t run rebuild to upgrade, because it’s a streaming operation. 
 Streaming isn’t supported between versions, although on 3.x it might work.

E.g. 2.2.x -> 3.0.x  but not 1.2 to 3.11

Heh, hit send accidentally.

You generally can’t run rebuild to upgrade, because it’s a streaming operation. 
 Streaming isn’t supported between versions, although on 3.x it might work.

Re: Upgrade using rebuild

[Anshu Vajpayee]

Thanks! I am aware with these steps.

I m just thinking , is it possible to do the upgrade using nodetool rebuild
like  we rebuld new dc ?

Has anyone tried -  upgrade with nodetool rebuild ?

Re: Upgrade using rebuild

[Hannu Kröger]

If you want to do a version upgrade, you need to basically do follow node
by node:

0) stop repairs
1) make sure your sstables are at the latest version (nodetool
upgradesstables can do it)
2) stop cassandra
3) update cassandra software and update cassandra.yaml and cassandra-env.sh
files
4) start cassandra

After all nodes are up, run “nodetool upgradesstables” on each node to
update your sstables to the latest version.

Also please note that when you upgrade, you need to upgrade only between
compatible versions.

E.g. 2.2.x -> 3.0.x  but not 1.2 to 3.11

Hannu
