Subject [jira] [Created] (CASSANDRA-6435) nodetool outputs xss and jamm errors in 1.2.12
Date Tue, 03 Dec 2013 00:22:35 GMT
Karl Mueller created CASSANDRA-6435:
---------------------------------------

             Summary: nodetool outputs xss and jamm errors in 1.2.12
                 Key: CASSANDRA-6435
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6435
             Project: Cassandra
          Issue Type: Bug
            Reporter: Karl Mueller
            Priority: Minor


Since 1.2.12, just running nodetool is producing this output. Probably this is related to
CASSANDRA-6273.

it's unclear to me whether jamm is actually not being loaded, but clearly nodetool should
not be having this output, which is likely from cassandra-env.sh

[cassandra@dev-cass00 cassandra]$ /data2/cassandra/bin/nodetool ring
xss =  -ea -javaagent:/data2/cassandra/bin/../lib/jamm-0.2.5.jar -XX:+UseThreadPriorities
-XX:ThreadPriorityPolicy=42 -Xms14G -Xmx14G -Xmn1G -XX:+HeapDumpOnOutOfMemoryError -Xss256k
Note: Ownership information does not include topology; for complete information, specify a
keyspace

ERROR 16:20:01,408 Unable to initialize MemoryMeter (jamm not specified as javaagent).  This
means Cassandra will be unable to measure object sizes accurately and may consequently OOM.
