Hello,
Recently we tried top integrate cassandra with NUMA
==
commented out the numactl --interleave in bin/cassandra and add
-XX:+UseNUMA to cassandra-env.sh.
==
But after inplementing, we saw HEAP and STACK values were changed to null.
#/usr/bin/numactl --cpunodebind=1 -- /usr/sbin/cassandra -p
/run/cassandra/cassandra.pid
#numastat -s cassandra
Per-node process memory usage (in MBs) for PID 13258 (java)
Node 0 Node 1 Total
--------------- --------------- ---------------
*Private 4205.18 4508.09* 8713.28
Stack 0.00 219.61 219.61
Heap 0.00 30.52 30.52
Huge 0.00 0.00 0.00
---------------- --------------- --------------- ---------------
Total 4205.18 4758.23 8963.41
Here you can see both Node 0 and Node 1 utilising 4GB. As per our
expectation NODE 0 Private should be zero. I
Is there any way to specify NODE-0 Private value change to 0?
Env,
RHEL7.3
3.10.0-514.2.2.el7.x86_64
cassandra30-3.0.6-1.noarch
Thanks
