I haven't had to deal with this problem specifically and don't know if
there is a storm specific solution, but the general Java way of dealing
with projects who have conflicting dependencies would be to either exclude
one of the conflicting dependencies using maven and see if it works,
otherwise
Dear all,
So, here is our setup so far:
- Ubuntu 12.04
- Cassandra 2.0.10, JDK 1.7.0_65-b17
- 6 nodes (EC2 c3.8xlarge/ 32 cores/60GB RAM, EBS disks for data,
ephemeral SSD for commit logs etc)
- pretty heavy write load - 100Ks/second
- RF=2, one dc, 2 racks
- everything works just
Just to clarify, does adding node include initiating a repair for the
cluster? Or you are simply bootstrapping a new node, nothing else?

No, simply bootstrapping. Basically, as soon as the new node starts joining
load average spikes like x10
And it's not like the load comes from streaming (judging from what I see in
visualvm), it's writes that start taking much more cpu, mostly for nio socket
select.

Hello, I've been trying to add a new node to my cluster ( 4 nodes ) for a
few days now.
I started by adding a node similar to my current configuration, 4 GB or RAM
+ 2 Cores on DigitalOcean. However every time, I would end up getting OOM
errors after many log entries of the type:
INFO
Since no one else has stepped in...
We have run clusters with ridiculously small nodes - I have a production
cluster in AWS with 4GB nodes each with 1 CPU and disk-based instance
storage. It works fine but you can see those little puppies struggle...
And I ran into problems such as you
Thanks a lot that is comforting. We are also small at the moment so I
definitely can relate with the idea of keeping small and simple at a level
where it just works.
I see the new Apache version has a lot of fixes so I will try to upgrade
before I look into downgrading.

Hi,
We converted column families from ST to Leveled Compaction strategy, but
build-in secondary indexes are not converted to Leveled Compaction. Is
there any specific parameter we need to define for Indexes or will it
derive compaction strategy from the primary table OR, Do we need to rebuild
I am using a datacenter in private network and want to replicate data to an
ec2 data center. I am confused which snitch to use so that my data in the
dc1 is replicated to dc2 in ec2 ? any help is greatly appreciated
thx

Srinivas,
Use ec2multiregion snitch.
