我正在尝试使用以下配置设置一个单节点 cassandra 实例以进行测试:
rpc_address: 10.0.2.108
listen_address: 10.0.2.108
endpoint_snitch: SimpleSnitch
seed_provider:
# Addresses of hosts that are deemed contact points.
# Cassandra nodes use this list of hosts to find each other and learn
# the topology of the ring. You must change this if you are running
# multiple nodes!
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
# seeds is actually a comma-delimited list of addresses.
# Ex: "<ip1>,<ip2>,<ip3>"
- seeds: 10.0.2.108
我已经通过多种方式更改了配置，但我总是收到 OutOfMemoryException:

最佳答案
这是 https://issues.apache.org/jira/browse/CASSANDRA-8116 解决的错误。在 2.0.11 中，可以通过将 rpc_max_threads 设置设置为默认值 Integer.MAX_VALUE 以外的值来修复此问题。
HsHA 服务器已更改，现在使用 rpc_max_threads 值来为每个选择器线程分配处理程序。因此，当它尝试分配 Integer.MAX_VALUE 处理程序时会出现 OOM
