Cassandra "nodetool status" fails with "Credentials required" after enabling remote JMX

Question

I followed these instructions "Enabling JMX authentication":

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

However I'm having this problem:

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

My configuration is this:

/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"

Maybe someone else faced same problem?

Cassandra Version: 2.2.1 JAVA Version: 1.8.0_60

Answer 1

Put the command at the end and the options at the beginning, like this:

nodetool -u cassandra -pw cassandra status
