[jira] [Updated] (CASSANDRA-6707) AIOOBE when doing select count(*)
from on a mixed cluster.

Via Sylvain,
bq. I think I know what the problem is: count(*) on 2.0 blindly use the new pagers and when it's a range query, this uses PagedRangeCommand which 1.2 nodes don't have. Not sure what's the right fix is. Probably just stick to non-paged calls if there is 1.2 nodes in the cluster, but that's slightly painful.
