-----------------------------------------

             Summary: Cassandra 3.10 jvm.options default -XX:+UseNUMA may core OpenJDK on some aarch64 machines at os::Linux::libnuma_init()
                 Key: CASSANDRA-13781
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13781
             Project: Cassandra
          Issue Type: Bug
            Reporter: Yangzheng Bai


We tried Oracle JDK, Linaro JDK, Zulu JDK and default OpenJDK, all of them cored at the same place: os::Linux::libnuma_init() -> os::Linux::rebuild_cpu_to_node_map()

Removed -XX:+UseNUMA option solved the problem. Therefore we should remove -XX:+UseNUMA as an default option on aarch64 machines because x86_64 and aarch64 may have different implementations on how NUMA is reported. And -XX:+UseNUMA is currently not supporting G1GC anyway (https://bugs.openjdk.java.net/browse/JDK-8046147), adding it as default option may not have performance gain for future Java default G1GC.
