Hi,
We're planning to deploy 3 cassandra rings, one in our datacenter (with
more node/power) and two others in EC2. We don't have enough public IP to
assign for each individual node in our data center, so i wonder how could
we connect the cluster together?
Have any one tried this before, and if t
ode, but you are repeating colName2 . Can you log

Hi,
I'm working on ColumnFamilyOutputFormat and for some reasons my reduce
class does not write all columns to cassandra. I tried to modify
mapreduce.output.columnfamilyoutputformat.batch.threshold with some
different values (1, 8, .. etc) but no thing changes.
What i'm having in my reduce class
Hi,
Is it the min_compaction_threshold and max_compaction_threshold? Do i
need to lower the memtable setting also?
Thanks,
Trung.

Hi,
I have a test cluster of 3 nodes, 14Gb of mem in each node,
replication factor = 3. With default -Xms and Xmx, my nodes are set to
have max-heap-size = 7Gb. After initial load with about 200M rows
(write with hector default consistencylevel = quorum,) my nodes memory
usage are up to 13.5Gb, sh
