Кассандра не может создать сокет для бережливости

Я не знаю, почему я не могу включить протокол экономии на кассандре.

в cassandra.yaml rpc_start=true port=9160.

ОС CentOS 7

iptables не работает

firewalld не работает

cassandra ver 3.7 (репозиторий datastax) запущена и работает.

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

JAN установлен

JMX включен

и т.д..

все в конфигурации cassandra в порядке, кроме файла подкачки, необходимого из-за нехватки оперативной памяти.

selinux не имеет значения, но разрешает.

я могу подключиться удаленно, но это результат nodetools enablethrift

Любая идея?

Я тоже могу «подключиться» с помощью Telnet к порту 9160.

netstat вывод:

tcp        0      0 10.10.30.11:9160        0.0.0.0:*               LISTEN      4395/java 

nodetool statusthrift => не работает.
