Hi,
We're running a small Cassandra cluster (1.1.4) with two nodes and
serving data to our Web and Java application. After up-gradation of
Cassandra from 1.0.8 to 1.1.4, we're starting to see some weird issues.
If we run 'ring' command from second node, its show that failed to
connect 7199
Thanks very much, Adeel! It works much better!

So what solution should be for cassandra architecture when we need to make

What we have now is fair amount of CFs ( 2K) and this number is slowly

In short the question is whether the row_cache_size_in_mb can exceed the heap

Yes.
AFAIK jna.jar is not required for off heap row cache in 1.1.X
My heap settings are 8G and new heap size is 1600M.
You can reduce the size of the
Not sure why you have two different definitions for the bars2 CF.
You will need to create SSTable's that match the schema cassandra has.

This is an issue with using the BOP.
If you are just starting out stick with the Random Partitioner.

How long is ages and how many nodes do you have?

Hi!

There are also messages of Finished hinted handoff of 0 rows to endpoint

If you are restoring the backup to get back to previous point in them, then you
will want to remove all hints from the cluster. You will also want to stop
recording them, IIRC the only way to do that is via a yaml config.

Is it still an issue if you don't run a repair within gc_grace_seconds ?
There is a potential issue.
You want to make sure the tombstones are distributed to all replicas *before*

Not sure.

Cool.
Just keep an eye out for how big the lucene token row gets.

The problem was - I calculated 3 tokens for random partitioner but
used them with BOP, so nodes were not supposed to be loaded evenly.
That's ok, I got it.
But what I don't understand, why nodetool ring shows equal ownership.
This is an example:
I created small cluster with BOP and three tokens

I did wait for atleast 5 minutes before terminating it. Also sometimes it
results in server crash as well, though data volume is not very huge.

In the process of trying to streamline and provide better reporting
