Subject [jira] [Created] (CASSANDRA-9019) GCInspector detected GC before ThreadPools are initialized
Date Mon, 23 Mar 2015 16:43:12 GMT
Philip Thompson created CASSANDRA-9019:

             Summary: GCInspector detected GC before ThreadPools are initialized
                 Key: CASSANDRA-9019
             Project: Cassandra
          Issue Type: Bug
            Reporter: Philip Thompson
            Assignee: Yuki Morishita
             Fix For: 3.0

While running the dtest {{one_all_test (consistency_test.TestConsistency)}}, I ran into the
following exception:

java.lang.RuntimeException: Error reading: org.apache.cassandra.metrics:type=ThreadPools,path=request,scope=ReadStage,name=ActiveTasks

Dtest didn't preserve the logs, which implies that this wasn't in the system.log, but printed
to stderr somehow, it's unclear with all the piping dtest and ccm do. I have yet to reproduce
the issue.
