Hi,
I am running Cassandra 2.0.5 on my PC (with just one node and the default
cassandra.yaml).
I have inserted one million rows into a column family (each row has a int key,
two small set<string> columns.)
In cqlsh, when I did a select count
cqlsh:testks> select count(*) from ips_table limit 2000000;
I got the following exception :
ERROR 16:04:05,657 Exception in thread Thread[ReadStage:66,5,main]

Are there some Cassandra parameters I could set to get ride of the above
exception ?
Thanks in advance for any assistance !
