We have also came across this issue in our dev environment, when we upgrade
Cassandra from 1.1.5 to 1.2.1 version. I have mentioned this issue in few times
in this forum but haven't got any answer yet. For quick work around you can use
pig.splitCombination false in your pig script to av
Since last night I am seeing CPU load spikes on our cassandra

After trying every possible combination of parameters, config and the rest,
I ended up downgrading the new node from 1.1.11 to 1.1.2 to match the
