how much memory can be allocated to Cassandra in DSE with spark enabled?
<p>Currently my DSE Cassandra uses up all of the memory. And therefore after some time and increasing data amount the whole system crashes. But spark and ops center and agent etc also needs several G memory. I am now trying to only allocate half of the memory to cassandra but not sure if that will work. </p>

<p>This is my error message:</p>

<pre><code> kernel: Out of memory: Kill process 31290 (java) score 293 or sacrifice child
</code></pre>
