Hi.
I was upgrading my 3 node testing cluster from 2.0.1 to 2.0.2. I
successfully upgraded two nodes but the last one did not shutdown properly.
Does somebody see anything suspicious in the attached thread dump?
Regards,
Mikhail.

mmm, cassandra normally resolves the name to the IP address and binds to that.
So it should just work if you are using localhost and that’s setup correctly.
Can you just use 127.0.0.1 ?

As I understand it, where clauses only apply to primary keys and secondary
indices.
I’m a little old fashioned and say if there is a query you do as part of a hot
code path it should be supported by materialising a view at write time rather
than using secondary indexes. That will give you
This one is coming out soon. Looks interesting:

Beside that , I found the already mentioned docs on the Datastax site to be the
best information.

Rack1 goes down and some writes happen in quorum against rack 2 and 3.
During this period (1) writes will be committed onto a node in both rack 2 and
3. Hints will be stored on a node in either rack 2 or 3.

Hi,
So you had to kill -9 the process?
Is there something interesting in system.log?
Can you restart the node or are there any errors on startup?

Too many open files are common if you haven't set limits properly

But it this case it might be a file descriptor leak.
This link can help and is still relevant for C* 2.0:
That would be a bug. If you could open a ticket on JIRA, that would be
great.

Just want to know whether the $subject is recommended. Because, I've seen
some of the Oracle(Sun) specific packages sun.misc.* are being used in a

Looks like a bug. See

We're working on upgrading from 1.0.12 to 1.1.12. After upgrading a test
node I ran into CASSANDRA-4157 which restricts the max length of CF names
to = 48 characters. It looks like CASSANDRA-4110 will allow us to upgrade
and keep our existing long CF names, but we won't be able to create new CFs

Hi, all -
I'm currently managing a small Cassandra cluster, several nodes with local
SSD storage.
It's difficult for to forecast the growth of the Cassandra data over the
next couple of years for various reasons, but it is virtually guaranteed to
grow substantially.
During this time, there may
I think the Owns calculation isn't taking racks into consideration. The
fact that you aren't alternating racks (availability zones, with EC2Snitch)
is what is causing the imbalance. I suggest either using the same rack for
all nodes (preferred) or alternate your racks/AZs: 1b, 1c, 1d, 1b, 1c,

I can't comment on the technical question, however one thing I learnt with
managing the growth of data is that the $/GB of tends to drop at a rate
that can absorb a moderate proportion of the increase in cost due to the
increase in size of data. I'd recommend having a wet-finger-in-the-air stab
No we're using vnodes
