bootstrap & rack aware on Cassandra4.1
Hi all, we experienced that writing on a rack aware node we get the
following error:
ERROR [pool-1-thread-1] 2009-10-30 15:48:55,467 StorageProxy.java (line
179) error writing key 13345671

We haven't understand how bootstrap works in Cassandra and how to enable
or disable it.
With trunk version everything works properly.

Sorry, maybe I missed the version , I am using the 0.4.1-snapshot, which is
build from the SVN code, maybe this is the root cause of "Rack-aware
bootstrapping not supported...".

RE: bootstrap & rack aware on Cassandra4.1

Yes we already tried your suggested configuration but it doesn't work: every time we try to write to a rack-aware node we get the exception: java.lang.UnsupportedOperationException: Rack-aware bootstrapping not supported... It's really strange to me that this config is working on your environment, maybe we're missing something but I can't figure out what and where... in the meantime we're trying the workaround suggested by Jonathan.

Re: bootstrap & rack aware on Cassandra4.1
Posted by Jonathan Ellis <jb...@gmail.com>.
Oh, I misunderstood -- you're not trying to bootstrap, but getting
this error anyway.
I'd probably call this "wontfix" for 0.4 since the fix is basically
all the work on ReplicationStrategy that's been done for 0.5, which
shouldn't be backported to a stable release imo. The silver lining is
that 0.5 will be out soon.
If you want a workaround in the meantime, make
getWriteStorageEndPoints just return getReadStorageEndPoints(token)
which will not treat bootstrap nodes correctly but it should work fine
otherwise. :)

RE: bootstrap & rack aware on Cassandra4.1
Posted by Paderno Giampaolo <Gi...@yoox.com>.
Thanks for the reply, in the meantime it's possible to manage replica between two datacenter with 0.4.1 even without bootstrap? In other words is it possible to write on a rack-aware node? If so can you post me a sample configuration?
Thanks
