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

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.
