Hello,
We are getting OOM errors when querying a hive table that is backed by a cassandra column family (see below). Querying this cassandra column family from cassandra-cli works fine. I am assuming we have something configured wrong (we have a fairly vanilla brisk install). I saw some info on how to configure Cassandra to avoid OOM, but since the error is only on the hive side, I wasn't sure if that's where we need to change things. Could anyone offer some advice?
Thanks,
-B
(note that we get an OOM with or without the "limit 100":
hive> select * from idx_logs limit 100;
OK
