             Summary: Authenticating Jolokia using Cassandra
                 Key: CASSANDRA-14992
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14992
             Project: Cassandra
          Issue Type: Bug
          Components: Legacy/Core
         Environment: Cassandra 3.11.2

Ubuntu Xenial

Jolokia 1.3.7
            Reporter: Cyril Scetbon
            Assignee: Cyril Scetbon


I've noticed that when I run a long operation like a rebuild using Jolokia, I 
can no longer query Jolokia and get a timeout error even when trying to read a 
simple attribute like the Java version in use : 
{code:java}
jmx4perl http://cassandra-3.11.2:8778/jolokia read java.lang:type=Runtime 
SpecVersion
ERROR: Error while fetching http:// 
cassandra-3.11.2:8778/jolokia/read/java.lang%3Atype%3DRuntime/SpecVersion :
408 Got timeout in 180s
{code}
I also removed the default flag 
[-XX:+PerfDisableSharedMem|https://github.com/apache/cassandra/blob/cassandra-3.11/NEWS.txt#L769-L771]
 but did not get more luck.
