启用远程 JMX 后，Cassandra "nodetool status"失败并显示 "Credentials required"

Question

我按照以下说明“启用 JMX 身份验证”:

http://docs.datastax.com/en/cassandra/2.2/cassandra/configuration/secureJmxAuthentication.html

但是我遇到了这个问题:

nodetool status -u cassandra -pw cassandra 
error: Authentication failed! Credentials required

我的配置是这样的:

/etc/cassandra/jmxremote.password
cassandra cassandra

/opt/jdk1.8.0_60/jre/lib/management/jmxremote.access
monitorRole   readonly
cassandra     readwrite
controlRole   readwrite \
          create javax.management.monitor.*,javax.management.timer.* \
          unregister

/etc/cassandra/cassandra-env.sh
LOCAL_JMX=no

if [ "$LOCAL_JMX" = "yes" ]; then
  JVM_OPTS="$JVM_OPTS -Dcassandra.jmx.local.port=$JMX_PORT -XX:+DisableExplicitGC"
else
  JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.port=$JMX_PORT"
  JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.rmi.port=$JMX_PORT"
  JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.ssl=false"
  JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=true"
  JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.password.file=/etc/cassandra/jmxremote.password"

也许其他人也面临同样的问题？

Cassandra 版本:2.2.1
JAVA版本:1.8.0_60

将命令放在最后，将选项放在开头，如下所示:
nodetool -u cassandra -pw cassandra status
