I started with a test cluster, 3 x i2.4xlarge instances running 2.1.4 and Spark 1.2.2. I loaded a few sstables (using sstableloader) from one of my problematic production tables, and each test involved the following simple statement in the Spark shell: {code} sc.cassandraTable(prod_analytics_events, profileevents).take(100).foreach(println) {code} I then upgraded to 2.1.6, loaded about 100G of data, and downgraded back to 2.1.4. The net result is that 2.1.4 works with both the small and larger data sets, while 2.1.5 and 2.1.6 work only with only the smaller data sets. The larger set caused the hang in both cases.

I had uploaded heap dump when OOM occurred: Ah, you hadn't mentioned OOM. In that case it is _highly likely_ you are experiencing CASSANDRA-9549, which will be fixed in 2.1.7 released shortly, or you can run the patch version posted to that ticket as [~rstrickland] has.

In this case, turning down your concurrent_compactions settings in the yaml would resolve the problem for you, and let it catch up with compactions. If that isn't the problem, we would need, preferably, a CPU profile from an attached debugger, or alternatively a sequence of {{jstack}} and {{top -H -b -n1}} outputs to analyze. Along with your cassandra.yaml and log file.
